St. Petersburg's EDGE District keeps getting edgier. The Veytia family is taking over the Davidson Fine Art space at 1100 First Ave. N and transforming it into Red Mesa Mercado by the end of the year. This newest sibling to flagship Red Mesa and Red Mesa Cantina downtown will offer something fresh: They are flying in equipment from Texas that makes fresh corn and flour tortillas, which will be used onsite for their tacos and burritos as well as in a small retail market along with salsas and ceviches. Why the EDGE District? According to Peter Veytia, it's the most exciting area in town at the moment. For more EDGE news, see today's Taste section. — Laura Reiley, Times Food Critic
