Three Cheers for the Market Ave. Wine Bar. This place is great in any season, but what I love about it is the patio drinking. There is no better place to watch people in Ohio City. You have the (sometimes) train wreck that is the Great Lakes Brew Pub next door with a truly great wine and beer list at your fingertips (including the aforementioned GL products).
The staff knows their way around the wine list and can usually pull something wonderful out of their "by the glass" list for you to try.
