LTH,
Never shop Costco hungry, least not if you don't want to leave with 22-lbs of peanut butter and 9-lbs of deli sliced meat. To this effect I have a few proximity joints to the Nile's Costco, not destinations, but perfectly fine for assuaging over purchase hunger inducing pangs, Papa Chris hot dog stand being my usual stop. I am happy to have another arrow in the quiver in the form of Steve Z recommended 4 Hermanos Too.
$5 Tuesday special three tacos rice and beans, decent, if not great, griddled steak tacos with a choice of onion/cilantro or lettuce tomato, on doubled up tortillas, slightly moist rice and smooth refried beans. Comfortable, if basic, physical space and friendly efficient service. I plan on exploring the menu further, in particular the daily specials.
Enjoy,
Gary
