Cantina la Veinte is not your average nacho spot. More than a dozen kitchen workers, browning tortillas and simmering large vats of fragrant soups like caldo de camarón, scramble to stay ahead of the weeknight buzz. The contents of the two-page bill of fare features tortas — Mexican sandwiches slathered with black beans and topped with cod or braised pork and avocado. Patrons rave about the fideo seco, a classic Mexican comfort dish of thin noodles simmered in a spicy-sweet tomato chipotle sauce topped with creamy goat cheese and cilantro. An array of Mexican fare is precisely crafted here, and the prices match the glamorous setting.
