Just cross Armour Park (across from the ballpark) you'll find Jimbo's. It's a simple little neighborhhood bar where you can mingle with sports fans and catch a game, meet up with friends prior to a Sox game or continue the fun after leaving the ballpark. Service is fast and friendly, food is decnt when the kitchen is open, and it's probably the most well known bar in the area. It's convenience to the expressways and red line make it an ideal spot to check out.
Pros: close to ballpark, cans of beer!, inexpensive
Cons: little bit small, kitchen hours
