Philosopher's Stone. Philosophers... stoned. This is a drinkers bar. By that I mean where else on a Saturday afternoon can you find 50 - 60 year old men sitting at the bar downing beers and Jaeger shots while watching Ultimate fighting on the tube and heckling the bartender.
Lower than low-key. Keep one hand on your drink and the other on your wallet while inside. Outside there's a nice patio that wraps around the building and on sunny days there are a handful of people chatting with a beer. It's self service if you sit outside so you'll need to take turns sending someone in to get the next round.
