I finally got a chance to drop by the Santa Fe BBQ truck for lunch, currently scheduled to be in the parking lot at 600 Old Santa Fe Trail on Tuesdays and Fridays, and darned if it wasn't excellent.
Steve, the owner, has a commercial-grade mobile smoker in tow behind his truck, out of which he serves an array of beautifully smoked meats including baby back ribs, beef brisket, pulled pork, turkey legs, and hot links.
I only got the chance to try an applewood smoked beef brisket sandwich with his Santa Fe hot sauce (he also does a mild), and it was excellent on a big, squashy roll. The meat was terrific, I appreciated that it was properly fatty, a must for this kind of caloric splurge. But the thing that put the sandwich over the top was the optional pile of diced green chile he added, which he also keeps in the smoker. There was nothing delicate or dainty about this sandwich, it was a giant mound of meat done outstandingly well.
Although my mouth wants me to visit this place all the time, my mental cardiologist says it's probably not a super great idea, but I'll be excited to drop by every now and then.
