The grocery chain, franprix, has outlets every few blocks.   Most of them also have machines to make fresh-squeezed orange juice which seems to be very popular among the french.

We discovered that one of the nearby franprix also has a great breakfast deal.  A bottle of fresh-squeeze orange juice and a croissant, pain au chocolat, or other pastry for 2 euros.   Given this is France, the grocery store pastries are really good.  Did I mention it is a less than 5 minute walk from our permanent apartment?  I expect we will be getting plenty of Vitamin C this year!
