"Hours: Open from 11 a.m. Monday through Thursday and Sunday, with extended hours until 11 p.m. on Friday and Saturday. Closes at 4 p.m. on Sunday. Tacos Chiwas and Espiritu owners Armando Hernandez and Nadia Holguin continue their investment in downtown Mesa with Main Burgers, a colorful burger bar housed in a former Subway that held down the corner for more than 30 years. The menu is concise but thoughtful: three burgers, a hot dog, and a salad. The Chiwas burger channels its taco counterpart with layers of meaty richness from ham, roasted green chile, and caramelized onions. The Sonora brings heat with chiltepin and a costra de queso studded with bacon. Thick, semi-smashed patties anchor it all; crispy fries and briny pickle chips bring it home. In short, Main Burgers is family-friendly without being too tame — it has a steady crowd and music that still bumps. Must order: Chiwas Burger: beef patty, queso asadero, roasted green chile, caramelized onions, ham, house sauce, and lettuce on brioche." - McConnell Quinn
