My boyfriend and I will be spending a long weekend in Paris in mid-July. We are on a budget, so we're planning on buying several of our meals in grocery stores for picnics. I'm sure that there are many great groceries stores and markets in Paris, but do any stand out as really exceptional in terms of quality or selection? Particularly ones that would be close to major tourist attractions?
Also I am wondering, are there any unique food items in particular that we might want to check out? We are from the Bay Area so we can get freshly baked breads and great wines and cheeses at home. These seem to be the most commonly mentioned picnic foods, but I'm wondering if there are other specialities we could try?
