After hanging up the keys in late July, Qdoba’s roving kitchen is gassing up once again. According to the truck’s Twitter account, the taco slinger will feed hungry slackers bystanders during Sunday’s St. Patrick’s Day Dash at Seattle Center. Those festivities get underway at 8am; when exactly ’dobs is firing up the grill is forthcoming. But who needs such details, just know the tacos are free, amigo. Update: The truck will park from 9 10 to noonish.

You may recall the four-wheeled marketing machine made the rounds in the summer of 2010. If the truck’s Facebook account is to be believed, the St. Patty’s bash is the first stop of many. We’ll keep you posted.
