For many years one of the best authentic Mexican food I've ever had. Very reasonably priced. When I first went there 25 years ago it was a little converted hot dog stand. Now it's a nice sized restaurant. To go is a huge business. I always have either of the meats in a quesadilla and get a couple of tacos... More

La Costa in Oakley is one of our favorite spots to enjoy a delicious lunch, especially on Sundays after morning Mass. Food is always great, fresh made to order... service is crazy fast and atmosphere is very inviting. Very nice indoor sitting area as well as a very nice patio. I would definitely recommend this place to anyone looking for... More

FIrst, say the name correctly! They tell me it is La COSTA as in Costa Rica. Get in line only after you've gone over the choices on the huge board. Hungry... More

With counter service, it is more fast food than a restaurant with wait staff, but the food was reasonably priced, quickly prepared and tasty.

My wife and I are not familiar with Oakley. We were there with another couple to kayak at Big Break Regional Park and we were looking for a good place for lunch. We picked LaCosta based on the reviews on TripAdvisor. We each ordered some kind of tostada and a beer. My friend knows that I love good oysters so... More

How more authentic do you want to get? Most of the customers are Latino! the condiment bar has everything you need and the menu is large. barrito's, taco's, tostado's and more. the horchata is good.

Authentic Mexican food. Quesadillas are the best I have ever tasted. The carnitas burritos are also very good.

From a food truck to restaurants in Brentwood and Oakley, they've come along way. Great, authentic Mexican food. This in not some wannabe Mexican restaurant, a the real deal. Quick service, reasonable prices and great atmosphere make this our go-to place for a Sunday lunch or weekday dinner....Go and enjoy.
