Whether served as totchos or casseroles or simply dunked in a healthy dollop of ketchup, the versatile tater tot should qualify as its own food group. In honor of National Tater Tot Day, the SoMa StrEat Food Park trucks are turning their specials over to this humble ingredient, churning out dishes like tri-tip tots, loco moco tots, kokio poutine tots and sweet potato tot sundaes. Splurge on an all-you-can-drink ticket to try every beer in the house while you enjoy music by The Stu Tails and the thrill of a tater tot eating contest.
