In my little city, we have Mama Blues (owned by the Barnhills, the folks who started the old Barnhill's AYCE chain), and Ryan's, briefly known as Fire Mountain, which used to be a steak place that turned itself into an AYCE place.
I call these places "troughs," because you go to the feeding trough to fill your plate. It's always fun to count the ENORMOUS people bellying up to the buffet. They're usually eating when we arrive and still eating when we leave.
Nevertheless, there
are reasons to go to these places (which are NOT cheap!). First, you have kids, who are hungry and have to eat RIGHT NOW. Second, you have a large number of people who each want something different. Third, you're in a hurry and want to eat RIGHT NOW. Fourth, you're sick of fast food and want a salad and/or some veggies.
FWIW, our Applebee's used to be grim, but they have a new cook and the food has greatly improved.
