If you are lucky, you may have a very small group for your beverage seminar. My wife and I did a mixology class last month in Skyline. There was only one other couple in the group, and they had been invited by the bartender the night before, or or would have been just the two of us. Since it was such a small group, he used some higher end products than they normally do, and actually gave us 6 drinks instead of the usual 5.
