The broth at Sand Castle Diner tastes slow cooked and balanced, with sweetness from caramelized onions and a savory backbone. You get a molten cheese lid that stretches just enough, sealing in steam and flavor. Each spoonful brings toast, onion, and broth together perfectly.

Order it on a chilly night and you will understand the hype. The portion is generous without feeling heavy, and the seasoning is spot on. You will probably glance around and notice nearby tables ordering the same thing, smiling as the crocks arrive bubbling.
