Their choice for Colorado was, sorry to say, just stupid. It wasn't even sandwich that you can buy. You have to order a Denver omelette with toast and then put it together as a sandwich. Just stupid, when there are a zillion other possibilities which are real sandwiches. They went that way solely because it uses a Denver omelette.
I personally couldn't pick a favorite. There are many brew-pubs in the state, and most have really good pub food, which includes some signature sandwiches. Very disappointing that Zagat would ignore that treasure trove of possibilities. Definitely lowers their standing for me.
