3.5 stars,
I've only been here for events (mainly Yelp) or in the wee hours where it's late to remember exactly what the place was all about!
From what I remember, Augusta House offers a very laidback loungey feel and serves as a perfect last minute place for a get together with a large number of friends (extra * for this).
Drinks are decent at least in terms of the price, not much to write about the music as it's not my typical cup of tea, but the laid-back crowd makes up for it. Worth as much a visit as any bar in Kensington (whatever that means!)
