I've been going to Santa Rosa for years now - not only is it very convenient to my house, they (still) have a drive thru and the food is delicious!
I am updating my review because they have recently updated their menu. They've added quite a few items.
My Mom used to always order the combo with 1 chile relleno and 1 cheese enchilada, but would switch the enchilada for a 2nd relleno. Well, she doesn't have to do that anymore, because they've added a 2 chile relleno combo to the new menu! Hooray!
Most recently, I decided to try the new "super" rolled tacos - which are 5 rolled tacos with sour cream, guacamole, cheese and topped with carne asada. Wow, were they good! And very filling.
They still have the same friendly service and reasonable prices. The only downside is that they are only open until 9pm, so it's not a good place for a late night munchie run.
