Mad Mex is one of the top bars in State College because it has a great atmosphere, good drink specials and the best food.
If you haven't been there yet I would recommend it. They have a nice bar and restaurant seating inside as well as tables outside on nice days.
It could get a little pricey but the drinks actually have liquor in them and the food is much better than at other bars in the area.
Monday is their best night, $5 all you can eat burritos and $5 big azz margaritas.
