This is an absolute must-see. Fuzzy Thurston's Bar. Fuzzy is usually there, especially game weekends. Several of former players (including former Raven's players) will probably be there before and after the game. That's where they like to meet. I've been there and it is awesome. Nothing fancy, just a good ol' neighborhood bar. Here is the website:

Plus this place is right across the street from the Casino with the poker room.
Fuzzy's old joint was a lot better but this place is very nice too.
