Any particular recommendations for London? I feel a thirst coming on!

Happiness Forgets is one of my favourites for a classic experience.

Discount Suit Company has a cool vibe, a bit more party-like, I remember dancing a few times there (despite it being tiny).

Waltz is a new one that's a bit different, Japanese-style, their creations are quite unique and masterfully delivered.

Shapes is also very popular for some reason, though I don't really see the point of places that only do bottled cocktails.

In Shoreditch and adjacent areas there are many other ones.
