My sister and I are surprising my Mom with a trip to Chicago to celebrate her 55th birthday this weekend. (Yes, this weekend and we don't have reservations yet... shame, shame.) Any suggestions for a special place to take her? She is not a super fancy person or a foodie but does enjoy delicious food. I want somewhere that will make her feel comfortable and not worry about the price of the entrees. I would prefer for the ambiance to be "magical" (think Serendipity NYC) and the food to be yum, and not too fancy. Any suggestions?? Thanks so much!
