Finally got a chance to stop by the Houston Wine Merchant before leaving town and check out the place. They seem to have a nice selection (although you have to ask about most things because they don't have much self space) and carry stuff that I can't find at the big liquor warehouse here. The guy who works there was fun to talk to and seemed pretty knowledgeable. He also said they would be happy to order anything that could be obtained here (in Texas). Picked up a few things too: a limited edition rum, arrack, Indian cask strength peated whiskey, and Germain Robin coast road reserve brandy.
