Liquor store for unique brands?
Agree with the LeNell's reco. Address is 416 Van Brunt Street b/t Coffey & Van Dyke, in the Red Hook nabe of Brooklyn. Owner is great and so knowledgeable. Phone (718) 360-0838
For hard to find beers, I have found the best source to be New Beer Distributors at 167 Chrystie St. (212) 473-8757. I buy Hitachino there as they have the largest selection i have seen.
