That's pretty far out there. Escalante's in Meyerland has some VERY nice margaritas, and if you got some extra play money they have a top-shelf one, comes in a plastic mixer and will get ya super drunk! On the opposite, if you want just a CHEAP margarita try Los Cucos on Mon. and Tues. for $1.59 'ritas...they only taste okay but for that price you can get 5 and some AMAZING fajitas for $7.
EDIT: Los Cucos has raised their price on fajitas to about $10-$11, to match most restaurants. They are still worth it, but obviously I enjoyed getting very delicious fajitas for so cheap! =(
