We'll be visiting Boston next week with our 14-month old. We're staying at Stuart and Charles, just south of the Boston Common. We're looking for good eats within walking distance of our hotel, and also within walking distance of the attractions that we plan to visit: the NE Aquarium, the Children's Museum, and the Science Museum. Low cost but chowish places would be ideal, but we also would love your recs for mid-range and upscale restaurants that might be child-friendly early in the evening (before 6pm). And your favorite family-friendly North End Italian is appreciated!
