Its been 5 years since I lived there, but I used to be able to walk south/south east of the stadium to find less crowded bars after the game. Places I miss eating at:
Taste of Philly for cheesesteaks
Tokyo Bowlfor a spicy chicken and rice bowl; also the chain Tokyo Joes
Cherry Cricket for burgers (some as good in Chicago)
Southwest food in general
- Buckhorn Exchange has a different menu and some fun stuff on the wall but is pricey for what you get like others have said. If your just in it for the taste, personally I'd gamble on a random Mexican joint. As many Mexican places as there are in Chicago, I remember the average place in Denver being better (save Frontera) esp. for green chile.
