Hey, I literally was there just yesterday. My folks have a place in the restaurant row area. Anyway, I was looking for the same thing last Saturday for the NC State game. I asked around and did some research on the inter-ma-web, but I couldn't find a "Syracuse bar."
At the advice of my uncle (who is a Pitt alum and annoying fan), we all went to the Overtime Sports Cafe in North Myrtle. Solid beer selection, great food, and we found a large consortium of Syracuse fans. Tons of televisions, surround sound, and they even had the game on a giant projection screen (like 24 feet tall I think).
Keep in mind that any sports bar you go to in that area is going to be stuffed full of dirty Duke fans tonight, so make sure you get really, really drunk and belligerent.
