The champagne just keeps flowing at the Dom Perignon Sunday Brunch, offered from 10 a.m. until 3 p.m. every week in Ellyngton's, the elegant corner dining room at the Brown Palace. And the brunch buffet spread is just as sumptuous as the surroundings: There are stations that make waffles and omelets to order; stations that carve up huge haunches of meat and dish up fresh fish; salad and sushi stations; pastry stations overflowing with incredible confections. The buffet alone will run you $46.95, but since this is food fit for a king, you might as well treat yourself royally and fork over the $186.95 that will let you brunch with Dom.
