Nationwide Arena is a venue in or near Columbus that is most often used for Hockey
I like the Big Bank dueling piano bar because they play every song known to man and gives you a great selection of drinks. There are also a bunch of local college bars if you want the younger social scene.
R bar is a Hockey-themed bar, most of hockey fans would go there before or after a hockey game, Cantina is also a good place to get a little crazy with friends.
