Where to watch Super Bowl in Palermo

Sull ivans (Irish Pub) in Palermo Soho
Hippodromo Palermo - believe this is ticketed and sold out though
1175 Bar and Lounge (not in Palermo but not far)

I'd expect both to be very busy. It's on ESPN2 which all places that are sports bar will have so as long as it is open late on a Sunday you should be fine.

I would recommend going to Sullivans early to get a seat, if you can't get there early and it is too busy when you do arrive then i would recommend going up to Plaza Serrano which is nearby and has a collection of the type of bars that I imagine would be able to show this.
