Tavern on the Tracks is okay.. it's got your basic bar food, solid drink specials, and a old tavern feel. It's a Buffalo Bills bar and the Bills fans are something else. So be aware on Sundays in football season. You can expect this place to be crowded due to its location. Right off the Blue Line and right behind All American and Hot Taco.
Nothing really to brag about. I do enjoy getting the nachos. Their wings are okay too. Nothing special but it will fill you up. It has a nice patio with plenty of tvs. The bathrooms are small and most of the time not that clean. But this place isn't claiming to be some fancy hip new restaurant. Tavern has been here for awhile and has stayed the same.
I haven't had an issue with service. It's never been phenomenal but I don't really expect that walking in. Read some reviews and make your mind up. If you decide Taverns not for you then there are plenty of other places to look too.
