If you’re walking on 2nd Avenue in the East Village and see a line stretching around the corner to get into Professor Thom’s, you don’t need to check ESPN to see what’s going on. If it’s Saturday, there’s a Michigan football game, and if it’s Sunday, Tom Brady is playing against people 20 years younger wearing six fewer Super Bowl rings. This dark, slightly underground bar gets extremely crowded, so if you plan on eating giant plates of nachos covered in pulled pork and roasted corn, or you don’t want to shoulder past Michigan Greek life alums to get to the bar, you should make a reservation way ahead of time.
