What is the best, most popular restaurant in your city?

You know that restaurant in your town? It’s nothing fancy, but EVERYONE knows and it’s considered the essential “place to go”. Maybe it’s a mom-and-pop deli, or a hole-in-the-wall chinese place; whatever it is, it’s damn good. It’s so good and so many people know it, that it spawned a small sub population of people who think it’s “over-rated”. But most likely it’s good.

So what is it called, and in what city?
