UK's hippest cocktail bars
I'm looking for the UK's hippest cocktail bars for an article I am researching. The sort of bars I am after are run by bartenders who make great cocktails and give them their own twist. They are also bars where you can have the sort of night out you talk about for days afterwards.
In London the some bars that fit the bill are Casita, Callooh Callay and nights like the Last Tuesday Society.
I'm pretty London-centric so far, so any help would be massively appreciated, especially if they are outside of the captial.
