For some reason Newtown has always been one of the places I frequent most for 5 a 7. Not sure if its because its conveniently located, but I always start there with a group of people. The drinks are a bit expensive, but they have the two for one deal during 5 a 7.
The terrasse is especially nice during the summer. The service can be a bit shoddy at times, and the food marginal, but I mainly go for drinking and I suggest you do too.
Also, I haven't seen a place with this much turnover in staff in a long time. Every time I go there are new people.
