Taco Mac gets by because they have a gazillion televisions. If you want to catch a game or a bunch of them at once, Taco Mac is your place.
If you want to eat, I would suggest somewhere else. I will not say the food is horrible but it is very overpriced and just adequate. You will not be blown away by anything but for the price, you should be.
The do have the largest selection of draft beers I have ever seen. I usually have one maybe two beers in a sitting so I don't drink a lot. But I love a good craft beer and Taco Mac always has something new for me to try.
They do not take reservations so if you are with a group for a big game or on the weekend, plan to arrive really early or be prepared to wait a long time for a table.
