I just wanted to mention a place off the square in Murfreesboro called 3 Brothers Deli and Brewhouse. The are one, if not THE, best places to go in Mufreesboro to enjoy a beer. I think they have around 25 taps with a full bar. The food is awesome and the atmosphere is great too. I love just grabbing a seat a the bar.
They have plenty of live music throughout the week too. Here is their facebook link: Welcome to Facebook
I highly suggest checking it out!
