David Tunnell, who used to be management at MTV's Latin American operation, decided to leave corporate life in the early fall of 2002. By Thanksgiving he'd opened Dogma (the name inspiration came from pal Carlos Carreño), and by Christmas the outdoor shop was packed. Instant Biscayne hipster hangout. That's because Tunnell, who's from Los Angeles, went to some trouble to use only the best ingredients -- Vienna rolls, Hebrew National dogs, and real L.A. chili (which costs twice as much to fly in) -- for the defining Dogma experience: the chili dog. Three hundred of these will go on a slammin' lunch day, most to those kinds of fans you see in the Design District or at the more upscale boho clubs. Designer chairs, retro-contemporary décor, windows everywhere so the kitchen crew can converse with the customers in total equality. Prices: $2.45 to $4.50 (the latter gets you the burrito chili package, which actually has two dogs). Seven days from 11:00 a.m. to 9:00 p.m.
