I recalled seeing a bunch of brunch-related threads a couple months ago, and have linked them here:
"Best" Brunch places in the citySunday Brunch - Four Season/Ritz/Sig Room?Sunday brunch/lunch in River North?I can personally attest to the brunch at NoMI...while pricey, I thought the quality, atmosphere, variety & service were all top notch. The food spread was excellent, and while I've heard they're paring back on the size of the buffet for economic reasons, they did say they'll continue to offer the full, no-holds-barred spread for special occasions. So I'd imagine that they'll pull out all the stops for Mothers Day. They managed to hit the sweet spot between white-tablecloth-swanky and relaxed-leisurely-Sunday-brunch, which I really enjoyed. The view & sunlight from that giant overhanging window is nice too.
I've been to lunch at Carmine's once...it wasn't bad. Both the food spread and the seating were outdoors in the little covered courtyard between Carmine's and Tavern on Rush. The food was decent, the service was friendly, and it was about half the price as NoMI. But it definitely wasn't a write-home-about-it experience.
