Onda Hour: Happy Hour in Costa Mesa

Onda Hour is our weekday wind-down — Monday through Friday, 4:00 to 6:00 pm on the big open-air patio, under the palms and the thatched-roof bar.
Order a Casa Margarita, let the California afternoon do the rest, and settle in like you’re on vacation. Free parking, and no reason to hurry.

Happy Hour on the Patio in Costa Mesa

There’s a two-hour stretch on weekday afternoons when this place is at its best. The patio fills up slowly, string lights crisscross overhead, music carries from the thatched-roof bar, and nobody’s watching the clock. That’s Onda Hour.

We kept the list deliberately short. Rather than discount half the menu, we took a few of the things guests already come back for and cut the price hard — the Casa Margarita goes from $15 to $10, and a full plate of Onda Nachos from $13 to $9. The draw isn’t a long list of deals. It’s the patio, the food, and the two hours you didn’t plan on staying for.

Find us at 1870 Harbor Blvd in Costa Mesa, minutes from Newport Beach, with free parking on site. Onda Hour runs Monday through Friday, 4:00 to 6:00 pm, dine-in and bar area only. Walk-ins are welcome — and if you’re bringing a group, ask about the patio or our private dining and banquet rooms.
