I stopped at Rusty Taco (Greenville & University) on a recent weekday, thinking I'd grab a quick lunch. Wrong. Because they time-stamp your receipt, I can vouch for the fact that I ordered at 12:58, and didn't get my tacos until 1:36. As I waited (and waited), I watched the taco line operate -- they were working fast and hard, warming each tortilla on the grill and putting the tacos together as quickly as possible, but simply couldn't keep up with the demand. (As I was leaving, they said the wait was 1 hour. Yikes.) I'm sorry, but this place may be doomed by its success (to paraphrase Yogi Berra, no one will go there because it's too crowded). Anyway, to the tacos: the brisket was tender and had a nice mild flavor; the fish (grilled) was bland; the best was the pork, which was a great mix of tender meat and grilled rajas. The tortillas were quite good. No al pastor -- bummer. Overall, at $2 a pop, not bad; certainly, a nice low-end chowing addition to the area. But RT's tacos are not in the same ball park as Fuel City's tacos. The wait is really what killed the experience; a couple of people gave up waiting, got a refund, and walked out.
