Inspired by Mexico’s seaside cantinas, El Corazon de Costa Mesa features cuisine by Armando Martinez, recently executive chef at Red O, Rick Bayless’ superb Mexican destination in Los Angeles. Palapas and fire pits on the patio encourage a shorts, T-shirts and flip-flops mind-set. Signature spicy tuna tacos arrive sashimi-style on a thin jicama slice with a slaw of green mango, papaya and chayote and a dusting of sesame and crushed pepitas; margaritas blend flavors such as banana and mint. Also new are Saddle Ranch Chop House, a rock-western experience with rustic, oversized bar and mechanical bull—look for the stagecoach on the roof!—and Olive Branch Pizza/Black Knight Gastro Lounge. If you’re looking for tasty things to do in Orange County, this place is perfect for your palate.
