2 words: Rooftop Bar!
I have only ever drank at The Greenhouse Tavern, but the food, from what I've seen and smelled, looks up-to-par.
What I go for is the rooftop bar and patio area, which overlooks E 4th Street. It's a great set up. I sip on wine and enjoy the views of downtown Cleveland's coolest, most happenin' street. I never seem to have a hard time finding a seat. The vibe is great and the booze is better. The help is always friendly and attentive to your wants.
It's a great place to just hang out on the rooftop and have great conversation with friends. It's a great place for groups.
