It's mainly road food, and not much of that. The south-bound traveler on I-25 who doesn't want to wait for the culinary delights of Santa Fe should look for vittles in Raton Pappa's Sweet Shop, near exit 451, has a reasonable reputation. Tucumcari plays the comparable role for those westbound on I-40 Branding Iron Restaurant and Del's are adequate, and there are several other diners. Pickings on the overland routes are thin. Your best bet for food near Capulin Volcano is probably in Clayton; try one of the restaurants there and write it up.The Rabbit Ears restaurant in Clayton is a good place to get Mexican Food. The price is reasonable too. It's located on the NW side of town on Hwy 87.
