Casa de Onda Brings Modern Mexican Fusion and Coastal Cool to Triangle Square

Now open at Triangle Square in Costa Mesa, Casa de Onda is a sophisticated new destination for Mexican American fusion, coastal-inspired cocktails, and al fresco dining under the stars. Translating to “house of vibes,” the restaurant debuted Saturday, June 21, with nightly dinner service and a live DJ starting at 8 p.m.

Designed with a Tulum-inspired aesthetic, Casa de Onda features one of the largest patios in Orange County, with palapas, firepits, and lush greenery. The indoor space is modern and serene, with a palette of soft grays, white, and black, accented by limewash finishes and atmospheric lighting in seafoam blues and greens.

The bold, Latin-rooted menu is crafted by Executive Chef Ryan Perez, a SoCal native and California Culinary Academy alum whose resume includes Bouchon Beverly Hills, CUT, 5 Feet, Alan Wong’s, and Bottega in Yountville.

Standouts include Shrimp & Grit Frites with chipotle ranchera sauce, Oaxaca Mole Braised Short Rib, and Asada Vampiro Tacos with a burnt cheddar crust. Dessert gets a twist with Tres Leches Cake topped with yuzu curd, praline, and fresh raspberries. Guests can also enjoy vibrant shareables like Shrimp Ceviche with mango-lime vinaigrette, Loaded Nachos, and a Chips & Salsa Flight.

Cocktails are playful and polished, with house infusions and regional spirits. Highlights include La Jefa (a luxe margarita with Don Fulano Blanco), La Tóxica (jalapeño tequila, cucumber, mint), and Bad Bunny (mango, pineapple, carrot, tajín). A curated selection of tequila and mezcal, wine, and bubbly spritzes round out the drinks menu.

Casa de Onda is located on the upper level of Triangle Square at 1870 Harbor Blvd. in Costa Mesa. Open for dinner nightly at 5 p.m. and lunch on weekends starting at noon. Brunch launches later this summer.
