Wesley, since you live in a big college town (and you’ve talked about being a student before), I’m guessing you have a lot of affordable all-you-can-eat options around you! The problem with buffets is the food quality can sometimes be mediocre (or worse), but you can make up for that in sheer quantity and also selection. The temptation is always there to make a pig of yourself, but you seem to have a good attitude about having a variety of choices, so the best thing is to enjoy a little bit of everything there, and not end up leaving mounds of food on your plate to be wasted. (This is a major pet peeve of mine when people do this.)
Chinese buffets often bring out sushi, crab legs, prime rib, raw oysters, and other delicacies if you go for dinner instead of lunch, so that may be an option. Dinner almost always costs more as a result, though. In Florida, we have the Golden Corral, which serves up buffet-style home-cookin’. Again, not the greatest food in the world, but certainly not bad, especially if you’re a poor college student. Sonny’s Barbecue isn’t a buffet (although their salad bar is, and it isn’t bad for a barbecue place), but they will bring you unlimited plates of barbecued meat, fries, garlic bread, beans, and cole slaw if you catch them on the right nights. And there’s nothing I love so much as barbecue in large quantities!
If you’re feeling adventurous, seek out some Thai or Indian restaurants that might have buffets, and try exotic new things! I haven’t had either cuisine very much since my friends aren’t culinary risk-takers like I am, so buffets are the best way to introduce yourself to new tastes and foods you haven’t had before. This can be a very good thing to do on a date, in a group of friends, or even go by yourself first to become accustomed to stuff, so you seem like an experienced “native guide” when you bring a girl or the guys around to the place.
(Of course, I generally don’t recommend all-you-can-eat buffets as a place to bring a date, but if the girl seems into it, you’ve got a good one!)
