Brunch in Lakeview/Lincoln Park?
Jack's on Halsted (Belmont and Halsted) - very good food with a calm, relaxed atmosphere.
Orange (Clark, just North of Belmont) - good, kind of funky food. Known for pancake flights, frushi (fruit sushi) and squeezed-to-order juice combos. Beware - on the weekends the place is packed and there are long waits.
Ann Sathers (Belmont) - known for their cinnamon rolls.
Joey's Brickhouse on Belmont has $12 AYCE brunch on Saturday with $1 drinks (mimosa, bloody mary's)...
food's not that great but... it's just such a great party atmosphere you can't beat it after 3 drinks...
o wait. n'mind. you specified Sunday.. uhhh.. drive down a wee bit to Sweets and Savories' prix-fixe. far superior to Ann Sather/Orange/Insert-over-hyped-brunch-joint-in-Chicago-here
