This was a great neighborhood bar - I often brought friends there and the food was good. Always crowded, good hockey on TV. The staff sucked but the rest of its good qualities compensated for it. It was tolerable UNTIL the bartender stole money from me by adding a large tip to my bill. I tried calling a few times and the manager acted like he was looking into it and never called back. I've submitted a dispute with American Express and hope to get my money back soon.
Moral of the story: don't go to Warren 77. If you still want to go, make sure you pay cash or pay with your Amex and keep your receipt until the charge is posted to your account.
Pros: Crowded, great food, good hockey
Cons: Staff sucks
