I fully admit I am very "stuck in a rut" when it comes to food. My refusal to try new things is rather ostrich-like in terms of sticking one's metaphorical head in the sand. And what's more, I *like* it like that. I see no reason to deviate from the same foods I eat all the time. 
In some areas, it's necessity: I plan my NYC trips around baseball - I go whenever the concentration of Yankee and Met games is high - and so usually I end up eating ballpark food (which, cost aside, is pretty good out there) for dinner. Although on those occasions when I am free in the evenings in New York, I don't go to chains. There is a place down in Greenwich Village that has AWESOME burgers, and is definitely not a chain. Plus there are the pizza places I often talk about. Those aren't chains either. But now that I found those, I find that I don't really care for exploring.
