Well, there's only one reason you might want to go to this restaurant/bar. For a noisy, crazy sport-themed time with food that is not terrible. IT's not good, but I can't say it is terrible. So, if you want to be festive in a sports kind of way with a million monitors around you, then this is the loud place to be, I suppose.
If, however, you are looking for a pub with a few screens that has been around seemingly forever and is a Princeton fixture, then go to the Alchemist and Barrister (the A&B). The A&B has a pub feel, but with its oak bar and tucked away tables, huge selection of beer, decent selection of wine and food that won't win any amazing awards but is far superior to what is at the Sports Bar, this is your place.
Also, if you are looking for a Princeton establishment, the A&B is it. Let me explain a little something about the Sports Bar: Until about 6 years ago it was The Annex. A little bit dive, but students and faculty went there regularly for the $2 Happy Hours. It could get loud, but it had a certain charm. Flash forward. It becomes "Sotto," a painful attempt to go upscale with questionable Italian food. Shocker. Now it is the "Sports Bar" and it is still far from the classic that once inhabited the space.
In short, if you want better food, better beer selection, a more genuine "Princeton experience" and a better ambience (unless you want a blaring sports bar and, hey, sometimes we do), then just say no. Walk a block down, turn onto Witherspoon, walk through a half alley and something better awaits.
