RJ Grunts in Lincoln Park has a really good cold buffet (salad bar), which is even better on Sundays. Nowadays, I think you can add a protein option (grilled chicken or steak) to the salad bar.
BJs on the south side (several locations) has good southern-style buffet.
Apparently, Trattoria No. 10 in the Loop offers a bar buffet for $12. I haven't had it, but I do like Trattoria No. 10.
Oh, and please please please don't miss the Red Apple for stick to your ribs Polish buffet. It's Old Country Buffet but (mostly) homemade and with that inimitable Polish feel. Great cold salads (beet, cabbage) and usually potato pancakes, boiled potatoes, rice, sausage, several kinds of chicken, fish, pork chops, and stroganoff type gravy dishes. Plus homemade cakes and cookies for desert and always fresh fruit. Yummy.
Last but not least is an inoffensive and inexpensive buffet chain called Sweet Tomatoes. It has a large cold buffet, plus about 6 hot soups, potato bar, breads, and a pasta bar. Be prepared for carbo-loading! It has only three locations in the Chicago area; the one near me is in Glenview, but also look in St. Charles and Schaumburg. Go to
www.sweettomatoes.com for info and menus.
