It doesn't take much for a first date to go bad. And for a vegan or vegetarian, there might be no quicker deal-breaker than when a potential love interest orders a steak at dinner. But single omnivores can avoid meat-induced mood-killers with Veg Speed Dating, a 45-minute whirlwind of three-minute rendezvous, followed by more mellow mingling and, of course, vegan food. The mixer, hosted by Karine Brighten Events, is aimed at heterosexuals 21 and over (an LGBT event is in the works) at Saturn Cafe (2175 Allston Way, Berkeley) on Wednesday, Aug. 3. 7:30 p.m., $30-$35. 510-269-7252 or VegSpeedDating.com.
