We get take-out from the McKellips Taqueria about once a month. The staff are always fast and the food is great.
The flying saucers are out of this world (heh) fantastic -- my fave is the chicken. Note: when I order a flying saucer for take-out, I always order an extra shell, because by the time the food makes it home, the shell can be rather soggy, which ruins the fun. They have always obliged and put it in a separate container.
The shrimp tacos (soft) and the rolled tacos (beef or chicken) are also great, and I love their salsa. The chips are a bit boring unless they are served hot -- then they taste great.
