This large and selective wine and spirit shop is very well stocked with top of the line wine, and an extensive selection of just about every kind of liquor you could ask for. The fact that it is in Mayfair should pretty much tell you the price range. This is not where you go to pick up cheap plonk on your way to some mate's mate's party, however it should also not stop you from going in and having a look as there are wines to be found in very acceptable price ranges. The staff are approachable and happy to help.
If the chichi wine puts you off (and it shouldn't), there are a plethora of spirits to shop for. I was thrilled to find some high end, hard to find, and much coveted mezcals from Mexico. For those in the know, mezcals, GOOD mezcals, are better then high end tequilas these days, and if you can find them, which at the moment in London is very hard, you should grab them! Like here at Hedonism. If that isn't your thing well then there are some very fine whiskeys, grappas, etc. to whet your pallet.
Definitely one of the finer wine shops in London.
