This is my favorite bar to go to when I want cheap food. Their nachos are amazing and their sandwiches are really good, as is their Sangria. Every day there's a different special after 5pm. Mondays - $2 burgers, Tuesday - half off sandwiches, Wednesdays - half off appetizers, Thursdays - $2 sangria. I rarely ever spend more than $10 (including tax and tip) and always leave full and satisfied. The crowd's the typical white young professionals crowd, but the wait staff is usually very nice, if not entertaining. Their website is unionparkchicago.com.
