Seems like your typical dive bar, so if you are also into that kind of thing then check it out. The bathroom was a little gross for my taste but eh that goes away after a few drinks.
The Oasis is the epicenter of New London's music scene. It is also the hippest little bar in New London, serving up 20 different draught beers (mostly microbrews, some locals, all awesome), the coolest young crowd around and impeccable music taste. Yes, impeccable.
