I've been to Greenhouse Tavern numerous times since my original review-visited the rooftop bar, eaten at the main floor bar and sat down for dinner at a table. Each time they've earned their stars. The service has been friendly and the staff is always willing to offer food and drink recommendations.
The food also stands the test. My favorites are the pomme frites served with aioli and the fall-off-the-bone chicken wings with scallions and lemon. Last time there, I tried the "Properly butchered rib steak," served with dauphenoise potatoes. It was large and very rich, but delicious. I almost always end with the maple walnut brittle ice cream. It's made by Columbus-based Jeni's Ice Cream and made exclusively for Greenhouse.
Definitely a must-eat if you're looking for a good place on in downtown Cleveland.
