Izzy's or Smitty K's are my two favorite places to go to watch sports.
Izzy's has good drink specials and the bartenders know how to make a good mixed drink. They have two gigantic projectors and other TVs around the place. And it is also rarely crowded. I have gone in there for a few Aggie games and several Sunday's for NFL watching. The only downside is they do not serve food their. You can, however, bring your own food.
Smitty K's has pretty good beer selection and I like the place, TVs everywhere. The food is actually really darn good. The only wings in town I will eat. The service is always good. It can get at times crowded in there and unfortunately on Fri and Sat nights they have live music which can be obnoxious but otherwise I love going there.
Last year, Smitty K's didn't have NFL Sunday Ticket. It is okay if the game you want to watch is on a local channel, but if you follow a team outside of Texas, your best bet is Fox and Hound or Buffalo Wild Wings. Maybe Razoo's might have Sunday ticket - I'd be interested to find out myself.
