An oasis in the desert of douchiness that is the Warehouse District bar scene. I lived next door for two years, and would "lock myself out" for an excuse to come here.
Go on a weekday, or earlier in the night. It loses some of its charm when it is jam packed. Pizze is the best in downtown CLE (although, that's not saying a whole lot), and everything is solid and affordable. Definitely pub grub, but good pub grub.
