An eight-ounce patty topped with mozzarella, grilled onions, and mayo is the kind of order that stops a conversation cold. That burger has a name, and it goes by the Superburger.
The building serving it wears plain brick walls and vintage Pepsi signs. Nothing about the outside announces a big deal, and I honestly love that about it.
Inside, blue walls and classic diner booths set a relaxed, small-town mood. The menu stretches from double cheeseburgers to slaw dogs to pizza, so picking just one thing takes real willpower.
I believe the best burger stops in South Carolina often skip the flashy signs and fancy toppings. This one lets a sesame seed bun, melted cheese, and a hot griddle do the talking.
So what turns a simple cheeseburger into the one everybody keeps bringing up?
The Superburger Is Big Enough To Need A Game Plan
Eight ounces of beef sits at the center of the most talked-about order at Pete’s Diner. That patty gets crowned with melted mozzarella, a pile of grilled onions, and a swipe of mayonnaise.
The combo is called the Superburger, and the name fits. Mozzarella isn’t the usual cheeseburger choice, which makes this one stand out right away.
Grilled onions bring a soft sweetness that plays nicely with the beef. Mayo keeps every bite from going dry, so the whole thing stays rich from start to finish.
Size is part of the fun here. Food writers have called the burgers at this Fountain Inn spot colossal, joking that you’ll need both hands and possibly a forklift.
No forklift is required, but napkins are a smart move. Grab a few extra before you sit down, because grilled onions love to escape.
A tip for first-timers: come with a real appetite or plan to share. Splitting a Superburger with a friend leaves room for a side or two.
Either way, it’s a burger that earns its spot at the top of any South Carolina diner wish list. Big, simple, and seriously satisfying.
Pick Your Cheeseburger Lane And Stay In It Proudly
Six different burgers fill the cheeseburger side of the menu, and every one of them keeps things classic. Nobody here is stacking donuts or sprinkling glitter on a bun.
The standard Cheeseburger comes on a sesame seed bun with lettuce, tomato, and mayonnaise. It’s the straightforward pick, and sometimes straightforward is exactly what the day calls for.
Hungrier? The Double Cheeseburger doubles down without getting complicated.
Bacon fans have their own lane with the Bacon Cheeseburger. Smoky, salty bacon on a cheeseburger is a pairing that never needs explaining.
Then there’s the Swiss Mushroom Burger for anyone who likes things a little earthy. Swiss cheese and mushrooms make a mellow, savory team that feels slightly fancy without trying too hard.
Food writers describing Pete’s Diner have pointed out the lack of gimmicks and fusion experiments. That’s the charm in a nutshell.
A smart move is to try one new burger on each visit. Start with the basic cheeseburger, then work your way down the list.
By the sixth trip, you’ll have a favorite and a strong opinion about it. That opinion will probably come up at dinner parties.
Chili, Onions, And Mustard Make A Messy Masterpiece
Homemade chili changes everything about a cheeseburger. At this Upstate diner, it lands on a sesame seed bun with onions and mustard right alongside the cheese.
That combo is a Southern classic for good reason. The chili brings warmth and depth, while the mustard adds a tangy little kick.
Chopped onions give each bite some crunch. Without them, the whole thing would be soft from top to bottom.
Chili cheeseburgers are one of the most mentioned items when folks talk about Pete’s Diner online. That says plenty about how this one fits the local taste.
Fair warning, though. Chili on a burger doesn’t stay politely in place, so this is not a first-date order.
Wear a shirt you don’t mind sharing with a little chili. Or eat it over the basket and let gravity do its thing.
Here’s a fun move for the indecisive. Order the chili cheeseburger and add chili cheese fries, which also show up on the menu.
That’s a full chili commitment, and honestly, it’s a respectable one. Just make sure the napkin stack is tall before you start.
Brick Walls And Pepsi Signs Keep The Outside Humble
Vintage Pepsi signs do most of the decorating out front. Behind them stand classic brick walls that look like they’ve been around a good long while.
No neon arrows point the way. No giant cartoon burger waves from the roof.
Drive by too fast and you could miss it completely. That would be a real shame, considering what’s cooking inside.
The plain look actually works in its favor. Writers have described the unassuming exterior as something that carries you back to a simpler time.
Old-school diners across the South often look exactly like this. Modest buildings with familiar soda signs were once the standard, and plenty of folks still find them comforting.
Here’s a tip worth remembering. Judging this place by its storefront is like judging a grandma’s cookies by the tin.
Slow down when you’re heading along South Main Street in Fountain Inn. Look for the brick and the Pepsi branding, then pull in with confidence.
Snap a photo of the signs while you’re there. They make a great little reminder of a burger stop that didn’t need a fancy front to win people over.
Blue Walls Inside Feel Like A Favorite Uncle’s Hangout
Blue walls set the tone the moment you step through the door. One writer described them as welcoming you like a warm hug, which is a pretty great job for paint.
Classic diner booths line the room. They’re the kind of seats made for sliding in, setting down a basket, and staying a bit.
Overhead, ceiling fans keep the air moving. They match the easygoing pace of the whole place.
The space has been compared to a favorite uncle’s rec room. It’s casual, a little lived-in, and not trying to impress anybody with designer lighting.
That small-town feel is a big part of the appeal at Pete’s Diner. Nothing here feels rushed or stiff.
For families, high chairs are available, so little ones can join the burger party. That makes a quick lunch with toddlers much less of a juggling act.
Want a booth? Arriving a bit before the typical lunch hour gives you more choice of seats.
Once you’re settled, the room fades into the background in the best way. Your attention goes right where it belongs, which is straight to the food.
Slaw Dogs And Pizza Are Waiting In The Wings
Hot dogs get mentioned more than any other item when folks talk about this diner online. That’s a surprising twist for a place known for cheeseburgers.
Chili cheese dogs are on the table too. They pair nicely with that famous chili.
Then the menu takes a turn toward Italy. Pete’s Diner is also listed for Italian food and pizza, which feels like finding a bonus level in a video game.
A veggie pizza has earned praise, with the owner, known as Ozzy, getting credit for making it well. It’s a nice option for anyone skipping meat that day.
Plates round things out. Country fried steak with potatoes, hamburger steak, and a chicken finger plate all show up on the menu.
Seafood fans can look at catfish and flounder plates. Hush puppies tag along with some of those orders.
With a menu this wide, a group can order wildly different meals and still share one table happily.
Sweet Tea And Crispy Sides Deserve Their Own Spotlight
Sweet tea in South Carolina is serious business. At this diner, the tea gets called out by name, with praise for both the selection and the sweet stuff.
A large sweet tea to go is a popular move. It’s the perfect road companion after a big burger.
Now let’s talk sides. Onion rings sit on the menu, and they’re a classic burger partner for good reason.
Corn nuggets are another fun pick. These little fried bites of sweet corn are a Southern treat many people outside the region have never tried.
Fried okra and fried squash bring some veggie variety. Sure, they’re fried, but they still count as vegetables in spirit.
Cole slaw shows up often too. It adds a cool, crunchy contrast next to hot, rich food.
Cheese sticks and chili cheese fries make good sharing snacks for the table. Order a couple and pass them around while the burgers cook.
Mixing and matching sides is half the fun here. Try something new each trip, and keep that tea cup full the whole time.
The Name Pete Has A Fascinating Upstate Backstory
Across the Upstate of South Carolina, the name Pete’s has appeared on numerous restaurants, many of them independently operated. Interestingly, some of those eateries were run by Greek immigrants whose names were Spiros or George rather than Pete.
Historical accounts describe how Greek immigrants built successful restaurant businesses throughout the Greenville area during the early twentieth century. Some began as pushcart vendors or candy-shop operators before moving into the lunchroom business, serving familiar American favorites like hamburgers, hot dogs, and sandwiches.
These restaurants often grew through personal connections. New arrivals could find work in a relative’s restaurant, learn the business, save money, and eventually open establishments of their own.
Rather than one unified chain, this history involved separately operated restaurants, with family and business connections linking some owners.
That history offers an interesting glimpse into how Greek immigrants helped shape the Upstate’s dining culture. However, the historical accounts reviewed do not establish a direct connection between that tradition and Pete’s Diner in Fountain Inn.
This Fountain Inn restaurant has its own appeal, with a menu featuring burgers and other familiar comfort-food favorites. Its Superburger gives hungry visitors a tasty reason to stop, even without a verified historical connection to Greenville’s earlier Greek-owned establishments.
Next time you spot a Pete’s sign on a South Carolina road trip, take a closer look. The name might be familiar, but each restaurant has its own story to tell.
Plan Your Burger Run Before Sunday Sneaks Up On You
Sunday is the one day the griddle rests. Pete’s Diner closes that day, so plan your cheeseburger cravings around it.
Monday through Saturday, the doors open at 10:30 in the morning. Closing time is 9 at night, which leaves room for lunch or a late supper.
Find it at 911 S Main St, Fountain Inn, SC 29644. It’s an easy stop when you’re passing through this part of the Upstate.
Not in the mood to sit down? Takeout and delivery are both available, so the Superburger can come to you.
Service has a reputation for being fast, which makes this a solid quick-bite stop. That’s great news on a busy workday.
One tip for delivery fans: burgers taste best fresh off the grill. If you can, dine in at least once to get the full experience.
Bring a friend, order something new, and save room for sweet tea. A plain brick building on Main Street has a lot more going on than it lets on.
