Check out Craigslist...you might not have to spend the evening alone.

West Town Tavern has a nice bar where they offer a full menu. It's a casual, neighborhood place...but food is contemporary American.

If you want to take a cab over to Wicker Park area, there are some cool "loungey" restaurants like Rodan and People Lounge. The restaurant Feast also has a bar that serves food.

Pretty much all restaurants in the city will serve food at the bar.
