I was able to make it to Andy Nelson's last Friday with a few friends and was very pleased with the buffet. It's more of an all-you-can eat, as you order what you want from the counter and then go back to order more, as opposed to the food in steam trays.
They offered the pulled pork, ribs (wet or dry), hot wings (bbq'ed, not fried) and bbq chicken (smoked). They did not offer the brisket, pulled turkey bbq or the southern pit beef. All sides were included (slaw, excellent bbq beans, potato salad and moist, sweet cornbread) except the fried potato wedges. Also included was a huge bowl of peach cobbler (more like peach crisp) topped with vanilla ice cream.
The pulled pork was tremendous. Very juicy and smokey and not the least bit dry. The vinegary sauce was a great compliment, though I also liked the mustardy sauce. The dry rub ribs were a little salty for me, but the traditional bbq sauce fixed that. I liked the wet ribs much better as the dry rub ribs were not falling-off-the-bone tender. The hot wings were pretty good, and not super hot. Juicy and meaty and much better than the smoked chicken which while not dry, didn't have a great flavor, though I'm not much of a smoked chicken fan.
You could go back as often as you wanted, and they gave you two meats and two sides per trip. Fountain drinks were also included for the $14 or $15 price.
While we may not have had the full price worth of BBQ, we had a lot of good food and were able to try many things for a lot less than if we ordered ala carte. They also had raffles during the buffet (5-9pm) and gave away Andy Nelson hats and gift certificates).
Overall, a very good time.
