A very unpretentious upstairs bar right next to The Boat in Kensington. I was there on 90s night a few Saturdays ago and had an excellent time. I feel like it was mostly getting spillover from the overcrowded Boat, but that wasn't a bad thing.
The 90s music was great, the crowd was chill, the bartenders were attentive. It wasn't too busy so go elsewhere if you're looking for a big crowd, but head to Augusta House if you're looking to get your groove on with some friends.
