DBA. DBA. DBA. DBA. DBA.
If I had to recommend one place for Single malt in NYC. It would likely be....anybody want to guess? DBA. It can get stupid crowded (it is NYC, after all) so get there early, get yourself a table with some friends, bring a bunch of cash, and have fun. I don't recall what I was drinking there, but it was old, rare, painfully expensive, and solidly one of the most enjoyable drams I ever drank in a bar. The pour was also a nice healthy, friendly "bar pour" not one of these moisten the bottom of a snifter measured out "shot" pours that some of the fancier places will serve you.
I do recal being amazed that I was served scotch in an old fashioned glass, not a proper spirits or nosing glass, nor even a snifter. Now, it is not a fancy bar, so I don't know why I excpected one, but with a scotch list of that caliber, there should be proper glasses. perhaps if you ask for one specifically they will oblige.
Enjoy. make sure you drink water between drams to cleanse the palate. If you want to wait till The weekend of March 3-5, I'll join you. Maybe we can find a nice spot for a smoke before or after.
