Located inside the Grand Central Market, Tacos Tumbras a Tomas is known for their carnitas, birria, and barbacoa but legendary for their heaping helpings. Tacos are more expensive than some other spots, but you essentially get two tacos for every one you order, as they pile on the meat and add extra tortillas as well. This place has prospered in this spot for a long time for a reason and they count many fans among the downtown taco cognoscenti. These tacos would have benefitted a hotter salsa, but overall were very tasty and filling.
