My older grandparents are coming to town for 3 days and I need some restaurant ideas. Being older, I'd like to find a place for them that honors reservations, is on the quieter side, bright enough and can accomodate older (although very hip) adults. Besides Tru or Spiaggia, any other ideas? They will be staying on Michigan Ave and must be able to take a cab to/from the restaurant. Thanks.
