This corner bar on a backstreet in Islington is so low-key that you might miss it or else wonder why anyone would recommend it. It's home to Tony Conigliaro, one of the U.K.'s foremost barmen. He creates the cocktails in a laboratory a few blocks away and you might scour London to find a list to compare to this one. If you want amazing cocktails served without attitude, this is the place.
Signature drink: Prairie Oyster (8.50 pounds).
