Tres Fuegos Cocina in Chula Vista's Otay Ranch area launched as San Diego County's first permitted Microenterprise Home Kitchen Operation, running a licensed residential kitchen at 2391 Eastridge Loop in the 91915 ZIP code. The MEHKO-certified menu centers on the signature Chile Relleno de Birria and a Short Rib Japanese Birria Ramen that fuses consommé-braised beef with ramen noodles—a cross-cultural build that draws from the same South Bay food-tourism circuit that includes waterfront dining near Chula Vista Bayside Park. A Latino-owned and women-owned operation, the kitchen holds a San Diego County Environmental Health score of 100 out of 100 and caps weekly output at 90 meals under the MEHKO regulatory framework. Corporate lunch catering and private-event bookings now supplement the curbside-pickup model, with party-sized formats that pair birria tacos, pozole, and flan alongside brick-oven builds from Chula Vista pizzerias such as Zappy Pizza. The birria ramen layers a 12-hour short-rib braise in a chile-and-tomato consommé over wheat noodles, topped with hand-pulled shredded beef, cilantro, and a lime wedge—a bowl engineered to bridge Mexican birria tradition with Japanese ramen technique.
