By far, I can say Ive been t hundreds of Denny's restaurants, but none of them can compare to the feeling you get at the one on 137th.
Im not a burger fan, but they offer the best ever!! its all in the bread. The dont use regular buns, they use potatoe bread, and ALWAYS butter the bun, it completely changes the taste of the burger.
The service can alter by individual, but LUIS H. is the best in comparison.
