tacos sibilia is tastier and cheaper. like big truck tacos, tacos sibilia has a taqueria location and a truck.
however, big truck tacos is expensive, but tacos sibilia, a guatemalan restaurant, is much less expensive and has a long list of daily specials that are delicious. i enjoy the fried plantains, caldo de res (beef soup), tortas, tacos, and anything that i try there. i went to big truck tacos once and will not return after the taco bell like burrito, but i will keep returning to tacos sibilia
