The “Flea Markets” on Airline Drive in North Houston form a giant mercado that draws some 50,000 Latino shoppers every weekend. Each flea market has its own taquerias and food stands.
De Buey Y Vaca is the most famous taqueria. (Buey y vaca means ox and cow, or steer and cow.) My favorite dish there was the barbacoa soup. Barbacoa soup belongs in the family of menudo, posole, and caldo de res. It’s a weekend breakfast soup eaten with a squeeze of lime, chopped onions and cilantro and a stack of tortillas. If you like barbacoa, this stuff will knock your socks off.
