This doesn't do you a lot of good until next week, but if you enjoy tacos and bargains, you should check out Taqueria El Rapido, located next to the Circle K at Benson Highway and Country Club on a Monday, Tuesday or Wednesday.
While it's not like the tacos are particularly pricey at $1.50 a piece, but since it's likely going to take three to make for a solid lunch, the 99 cent taco deal Taqueria El Rapido (which despite its name, is not all that "rapido") runs earlier in the week saved me $1.50, which was enough to get a Coke in a bottle as well.
I wouldn't say the tacos are spectacular, but they're definitely solid, with tender meat and quality tortillas. I think I've worked my way through the entire meat selection at this point, and I haven't been disappointed by any of the options. Plus, the condiment bar has a good selection covering most of the classics of taqueria toppings: pickled red onions, a couple salsas, avocado crema, radishes, etc. I'm almost certainly biased by this truck's semi-proximity to the TW offices, but between the cheap tacos and the ability to double the net weight of my plate via toppings, Taqueria El Rapido might be one of my favorite places to eat right now.
