If you go to the pinned threads on the top of your this forum, you'll see one that says Rutgers Gameday Information. Lots of great stuff in there.
Personally, I'd try Stuff Yer face, Brother Jimmy's, and obviously the Grease Trucks. There are some other nice spots downtown as well. Easton Ave is where to go for the drinks. Stuff's and Brother Jimmy's both have bars as well. Other places include Kelly's, Olive Branch, Corner Tavern, and Hub City Brewhouse. Olde Queens, Scarlet Pub, and Knightclub are the popular bars for the youngins. If you want to stay close to campus, try the Hyatt. Could be a bit pricey though. Other options are a little further away, but not as expensive. If your setting up a tailgate, best options are to buy a parking pass or get to Johnson Park pretty early. Got an RV, go to the RAC. Otherwise, I'd walk around the Scarlet, Blue, and Yellow lots if you're looking for some awesome tailgates. We don't mess around when it comes to the pregame festivities lol.
