The Boro Bar and Grill

five, yes, five stars.  The Boro is as good as it gets for a little divey beer bar with food and a good-to-great beer selection.  Always dim and lit with the bare minimum of reddish neon, the place has something like 10-12 taps, more than half of which are generally very good choices.  On top of that, there are some 80-odd bottle selections, including a fine selection of European lagers that are becoming increasingly hard to find in the US.  They also carry a small selection of "high gravity" beers, meaning I believe that they must carry a liquor license, but nothing other than beer is served.*  

The food is great for the smallish selection of bar-type sandwiches and appetizers that they offer.  Very reasonably priced, the burgers are made from hand-formed patties that they grill up to order, and the simple sides like fries and onion rings are also excellent.  The only small gripe I have is that it would be too easy to replace the mealy white-bread buns with something slightly better.  [UPDATE 9/12:]  ((the sandwiches now come on highly pleasant little ciabatta rolls.  So therefore the Boro is now perfect.))

There has been a pretty steady turnover in bartenders over the last few years, unlike say five years ago when the staff was a lot more stable.  Still, there are generally 2-3 tattooed, college-aged women on hand to direct you to a tasty beer, grill up your burger, or take your request from their massive collection of tunes stored on an old PC behind the bar.  The music is typically very good classic alternative mixed with some classic rock and whatever's hot on the college radio blogs these days.  

For years this was, and arguably still is, one of my favorite bars in Tennessee.  Not much has changed in the 8 years I've known it.  And not much has needed to.

*((another, less important, update: they apparently have wine also, but I don't believe it's encouraged.  They have literally 8 wine glasses in the whole bar, and I'm pretty sure I've never seen them used.))

Cool new bar/restaurant in Murfreesboro near MTSU's campus. Not sure about the entertainment, but the food is good. The pizzas and specialty hot sandwiches are my favorite!

Go for the beer and the music. The music is awesome.
