The "Happier Hour" at Basil Canteen
(1489 Folsom at 11th St.) has an awesome menu of $5 snacks that captures the breadth of street-food offerings in Thailand, from Bangkok to Chiang Mai. The sai ouah
pictured is a cavalcade of flavor, as you layer slices of Chiang Mai curried pork sausage with peanuts, ginger, lime, peppers, and onion. Other cheap stunners include the sakhoo saimu
(pork and nuts encased in tapioca dumplings), peurk tod
(taro fries with sweet sauce), and giow grob
(fried shrimp and pork wontons). They're available Sundays through Thursdays from 5 to 7 p.m.
