If you score a sitter, head to North Pond, a gem with all the components of a perfect celebration spot. The romantic, Arts and Crafts-style restaurant sits beside a small pond in pretty Lincoln Park, and was originally a warming house for ice skaters. A path cut through the trees reveals an amazing, unobstructed city skyline. The food, too, is nothing short of stunning: seasonal eclectic-American dishes that emphasize organic and locally-grown ingredients. (You might find saffron-accented bouillabaisse made with line caught-cod and mussels, squab breasts in mace cream, or warm potato leek tarts.) Sunday brunch is more casual but not one bit less fantastic. 2610 Brunch (Sun), Dinner (Tues-Sun). (NOTE: North Pond serves lunch from June through September) Bus: 76 Diversey, 77 Belmont; 151 Sheridan. Average main course: $30.
