I'm with Mixed Grains. I love salad bars.
We all love salad bars--salad bars are NOT buffets though, LOL. Buffets have hot pre-cooked food, none of which will be prepared w/out added fat!
I'll argue a bit here. A buffet typically incorporates elements
of a salad bar, plus it has other stuff, most of which (but not all) tends to have added oils. Things commonly found on buffets in my area that usually aren't found on the local salad bars:
1) baked potatoes (sometimes has oiled skin, you have to check)
2) baked sweet potatoes (likewise)
3) boiled carrots (sometimes sweetened, only rarely oiled)
4) steamed or boiled brocolli or cauliflower
5) fresh pico de gayo (chopped tomatoes, jalepenos, onions, and cilantro)
6) cooked peas and corn or other mixed vegetables (sometimes oiled, but not always, you have to peer suspiciously or dredge some across a clean plate and inspect the streak for rainbow sheen)
7) steamed white rice still in the cooker
barbecue sauce (needs to be inspected suspiciously for oils)
9) more cut fruit than you'd find on a salad bar
and so forth. The buffet experience typically adds one or two starches, one or two vegetables, and one or two condiments that wouldn't be available in a salad bar environment.
A lot of careful scrutiny and discretion is required and it's not for everybody. But I'm not willing to accept the blanket suggestion that there's never any useful foods on a buffet. And of course my actual statement was that they work *better* for me than trying to make special off-menu orders -- which is a far cry from saying they are a perfect eating choice.
