For a convenient, neighborhood restaurant they need to have better food. The servers are friendly, the location is good but their food product is below average.
Dinner tonight: two uninteresting wrap sandwiches overloaded with lettuce and a Chinese chicken salad that was a pile of iceberg lettuce with a vague hint of some dressing, canned mandarin oranges and some cold dry grilled chicken breast. That's not a Chinese chicken salad.
You need a better chef to design a menu that's great; simple, tasty food prepared correctly and served well. That makes a neighborhood restaurant succeed, otherwise just be a bar.
