Biscuit head is stellar. The biscuits are slightly sweet--not too much, just a little taste--which I think sets off the fantastic ingredients on each biscuit. Country ham is my favorite--it's very salty and the red-eye gravy is amazing. I've also had the pulled pork, which is great as well.
You do typically have to wait in line for a while at Biscuit Head, but once you get to the butter and jam bar, it all seems worth it. I come here with my brother whenever I'm in town and when I'm not in Asheville, I daydream about it.
