Saying they have a great selection of beer, wine and liquor goes without saying. But, I like how I can usually stop any employee walking by and ask them a specific question about a wine or spirit and they know the answer. Friday night we stopped in to get a bottle of Rum and while we were standing there staring at a liquor we rarely drink a guy walked by asking if we were doing OK. We asked him about something specific and he actually knew what we were talking about! This happens more often than not, and if they don't know, they immediately find someone who does.
Their customer service is top-notch.
