I have family in town next week who are staying in the West 50s. What is a good place for Sunday brunch that is not too expensive (but not a diner), would be not too crowded and not too psychotic a scene? I am thinking along the lines of L'Express, but in Midtown. Just somewhere nice and cute where the wait would be minimal to non-existant (I think we'll meet around 11, so kind of early). Any suggestions?
