Taco Tuesday in Costa Mesa
Every Tuesday, Casa de Onda runs Tulum Tuesdays, our take on Taco Tuesday, on the open air patio on the second level of Triangle Square in Costa Mesa. Six tacos, $4 to $8, and four of them you cannot get here any other day of the week. Tuesday is also the only day we sell tacos a la carte, so you can build a plate across the whole list instead of picking one and wondering about the rest.
The patio is open air and under the palms, with the thatched roof bar at one end. It is the same room that runs brunch on the weekend and Onda After Dark on Friday and Saturday nights, just at a slower, easier tempo.

Four tacos you can only get on Tuesday
- Ground beef, $4
- Fish, $6
- Sirloin, $7
- Birria, $8
These four are not on the regular menu. They come off when Tuesday ends and they are back the following Tuesday.
Two menu tacos at Tuesday prices
- Pork, $4 on Tuesdays. It is $10 the rest of the week.
- Lobster, $8 on Tuesdays. It is $11 the rest of the week.
Tuesday is the only day we sell tacos a la carte
Every other day of the week our tacos come two to an order. On Tuesday they are a la carte, so you can order a single one of anything on the list. Order one of each if you like, which is rather the point of putting six of them on at once.
What to drink
- Casa Margarita, $10 all day
- Dos XX Lager, $6 all day
