Just got a carne asada burrito from this place, this may just be the best burrito I have ever eaten. Thanks you guys are awesome!

One of the few 24 hour places in San Marcos. Good for some late night eats. I'll usually grab a California or shrimp burrito from here on my way home if it's late at night. Burritos here are pretty good and it's close by the freeway.

This place is great especially since it is a 24 hour drive through. It's fast and convenient and the food is decently good. One of my favorites is the surf and turf burrito (asada and shrimp) - it's not dry; the shrimp is cooked perfectly and there is guacamole and I believe some salsa and carne asada in it. I like how they don't fill it with rice like some places do. It's also huge! Decent price (around $12) I can't speak yet for the other food but my husband likes their menudo. Service is quick and to the point. Ambiance is basic and nothing special but who cares? The food is good and does its job.

Been wanting to try Oscar's for awhile and my nephew, who was visiting, was craving late-night Mexican...so it was the perfect excuse. We ordered via drive through. We got: Adobada Burrito - nephew loved it and said he'd get it again. The meat was delicious. Carne Asada Taco - this was huge and really good. Came on a soft corn tortilla with onions and cilantro. Chicken Taco - this came on a hard shell with cheese and lettuce. We also ordered chips with guacamole and pico de gallo. We were surprised it was served all together in a container, like nachos without the cheese. They were good.

Wonderful beef and chicken enchiladas! Wish I could have waited for the churros! I'll be back!

Omg this place is so good. If you read my reviews, it's rare that I give 5 stars. This place is a hidden gem. Or maybe it's not. Everything that I tasted was so good! They had an open salsa bar!! Yes! The tacos and carne asada fries were on point! Will def come back here if I'm ever in the area! Wish they had one in Northern California!
