First of all I agree that Shochu Lounge should be kept a secret, although - by looks of the place last night - the secret has been out for a while. There were a lot of people there and many had more than a smidgen of meeeedja or City about them.
However, the atmosphere and service is lovely and the cocktails divine. We sat by the bar and the guys working behind it were charming and even gave us a free cocktail to taste (a lemony zesty kind of ice thing. Like sorbet. But better. And alcoholic). So, my tip is - go. But don't take a big group of people. This place is perfect for a date.
Apparently, shochu has medicinal benefits and doesn't give you a hangover. With regard to the medicinal stuff - I have no idea but I sure felt good. And the hangover? I felt great this morning but my date didn't. So, it's open to debate.
