I do not live in Chicago, but am planning a 60th bday celebration for my mother to be held in downtown. i could really use your help figuring out which great restaurant we should choose for her special day! Here are the criteria-Mom is vegetarian, tends to prefer Asian cuisines though she's open, there will be a lot of grandkids there so should be child friendly, we would prefer a place that has a special room for private parties, we're looking for someplace special so no casual recs please! Thank you in advance!!!
