I'm not so familiar with the brunch offerings around Rittenhouse, but I need to find someplace where 4 adults and 2 kids (9 &6) can have a nice, leisurely meal on a Sunday at around 1:00. I want someplace not super-expensive (i.e. LaCroix), but with a good variety of food, including for one of the kids who is quite picky. All I can think of is Marathon. Any other ideas?
