Am helping a friend book her anniversary dinner (it is their 16th anniversary) in Chicago over the July 4th weekend for Saturday, July 4th. Am looking for a place where above all, the food is excellent, but ambiance (i.e. not too loud, romantic a big plus) and service are important too. Have not been to any of these places, but here's what is being considered -- Perennial, Boka, Graham Elliot, and Mon Ami Gabi. They are also thinking about North Palm, but are worried it might be too stuffy. They wanted to go to Sepia, but it is closed for the holiday weekend. Of these choices, what would you recommend?
