An at-home bar guarantees cheap drinks, a comfortable seat, and the ability to entertain guests with your favorite Dostoyevsky novels on tape. Toast Russian genius with today's Groupon: for $139, you get a four-hour course in at-home bartending (a $315 value) at the Texas School of Bartenders on North Lamar Boulevard. Customers can register for classes on a Saturday from 9 a.m.–1 p.m., a Saturday from 1 p.m.–5 p.m., or a Sunday from 10 a.m.–2 p.m.

The award-winning Texas School of Bartenders educates aspiring mixologists on the fine art of bottle slinging and concocting eclectic elixirs in a laboratory of fully operational bars. Liquorious lessons begin with a one-hour lecture on home-bar setup (a $65 value), equipping house-party hosts for future mixers and more forgiving tax audits. Spend an hour chugging through the liquor dictionary (a $100 value) for increased beverage brainpower, then absorb an hour of gourmet bartending (a $100 value), where bottles are tipped and drink-dressing garnishes are assembled for 25 specialty cocktails. Like taking your classroom knowledge of calculus and applying it to splitting a restaurant check, the course culminates in 30 minutes of practical application and behind-the-bar action (a $50 value), allowing novices to try their hand at serving balanced drinks to bucking mechanical-bull riders. Each class accommodates 24 potential beverage builders.
