Tini Bigs is offering a class this Saturday for aspiring at-home bartenders intent on honing their craft. Tequila is the spirit of choice for this session, with drink-making demos, a discussion of technique, and cocktail samples. You’ll study up bar-side and be sent home with literature and recipes; feel free to call this “homework.” Consider the $35 class fee an investment in your mixed-drink repertoire. $35. Tini Bigs Lounge, 100 Denny Way, 284-0931.Sat., Aug. 29, 4 p.m.
