Fantastic taco truck. I visit every time they are in Uptown, usually in front of their now-opened but not as good cafe.
If I have any complaints, they are occasionally a bit slow and the tacos are on the small side. Get a bigger side, like the side salad, to help tide you over.
I can say I'd pay the $4 for an extra taco or would have no problem with being hungry again in 3 hours after getting their meal. The BBQ brisket taco is a favorite that contains plenty of meat. I never thought I would believe it but the buffalo-cauliflower tacos are shockingly good. Ingredients are well flavored and taste very fresh.
Their pork shoulder special may be one of the best tacos I've ever had. More on the expensive side for lunch on Tryon but certainly among the tastier available.
