I'm a big Khoury's fan. I think it's because it has that Mom & Pop feel while still providing an incredible selection of spirits to satisfy all tastes. I believe they have two locations. This one just happens to be closest to my house.
Every time I go in there, I am greeted warmly. And when I check out, I always get useful information on what I just purchased or advice on other things to try. In other words, the staff at Khoury's know their liquor!
Bonus 1-up info: They typically have free wine tasting on Wednesday evenings from 6-8pm. I've only been once though. What's wrong with me?
