The scent of garlic, chilies, cilantro, and other quintessential Tex-Mex flavors waft through Diablo Southwest Grill’s two stories, where waiters ferry bowls of rich chicken enchilada soup. The menu also includes Cowboy nachos with chili and bacon, hamburgers topped with guacamole, and the Socorro steak sandwich with chopped chilies, blue cheese, and whiskey-onion sauce. Bartenders pair drinks with each dish, from classic margaritas and manhattans to the Mexican beers on tap.
