The San Antonio Cocktail Conference is one of the most highly praised events of its kind, even though it's relatively new. Held over an extended weekend each January at several downtown venues, the conference features tastings of various libations and food from the best restaurants, as well as dancing, seminars and other events. And perhaps the best part of all is that the proceeds go to benefit local charities.
If you go:
Tickets may be purchased in advance online, and you may purchase tickets for separate sessions. Nonalcoholic cocktails are often available if you're a nondrinker.
