Weekday Taco Trucks A full hour of weekday examining the Seattle Taco Truck Phenomenon. Guide to Taco Trucks Personally, I've found that the best burritos are at the Taqueria Guadalajara on 148th in Bellevue (just off 520). $3.25 each (they offer cheese, but I think it's mainly to appease the Taco Bell crowd...) Their tacos are also pretty good, though the azada can sometimes be a bit bland and chewy. Found the best Azada tacos at a place in downtown Monroe (on Main Street across from the 7/11.) 1.00 each, plus they offer all kinds of authentic meats (Cheek, Brain, Tongue.) The azada is thin sliced and pillowy with amazing flavor. Their burritos are only OK, but at 2.50 each, I can't really complain too hard... Well, that's the view from the Eastside anyway...
