Many of my friends prefer the Blind Pig, but Mike & Molly's will always have a very special place in my heart. For the four years I lived in Champaign, it was my go-to place for a beer on the way home from campus, a quiet divey place to hang out and do homework, or the place to go with my coworkers after the coffeeshop closed.
My review is obviously colored by the many, many nights of hanging out with friends or dates or both, so take my five stars with a grain of salt. My partner just sleepily informed me that it's definitely a four star bar because it's too small inside, but the patio's great. I'm sticking with my stars, though, because of the great and always-changing bottle selection, bartenders who are just as friendly (or not) as you want them to be, and the bar frat, which still seems like a random idea to me.
