Nookie's actually has three locations: the original Nookie's in Old Town, Nookies Too in Lincoln Park, and Nookies Tree (the only one I haven't been too). They offer a great breakfast for a great price. Casual, family-type atmosphere.
Favorite Dish: I love the Dixie Benedict - two poached eggs over ham and two biscuits, covered in sausage gravy.
In the heart of Boystown, Nookie's Tree is a glorified diner, but the food is great and it's probably one of the best low-key and low-cost brunch places in the neighborhood.
Favorite Dish: Anything on the brunch menu is worth having!
