There is nothing bad I can say about the Wine Bar. Its quiet, romantic, and full of the best wine you can get in Cleveland. The staff can recommend a good wine depending on your mood and taste (esp Nick). Their light appetizers and desserts are absolutely scrumptious.
I recommend:
Any wine on the list
Baked Brie
Tampenade
Chocolate Truffle Cheesecake
Avoid:
Large groups
Overall: Raise your glasses and toast to Market Avenue Wine Bar
