My husband and I are arriving for our first trip to Paris on the first Sunday in May. We're celebrating our 30th anniversary the day after we arrive. My first question is where could we find a nearby market to buy water, bread, cheese, picnic supplies? We are staying at the Prince de Galle hotel on George V with starpoints, and we want to be somewhat careful with our money, balancing between some special dinners out and inexpensive picnics in beautiful, romantic areas. I understand a lot pf places will be closed on Sunday. Secondly, do you think Le Train Bleu is a sufficiently special and romantic rstaurant to celebrate our actual anniversary night in? Or do you have any recommendations for how to spend our actual anniversary day? Thanks!
