I definitely agree with all. being French, I absolutely HATE doing my grocery shopping here as I don't find any quality food. In quality, I mean good taste.
However, compared to the stuff in the US that is 100% artificial, this is heaven. Most of the stuff here is local, fresh, and natural.
When I want something better, i just cross the border and go to Billa in Kitsee. For example some fruits and vegetables not available here, great steaks for the grill, etc..
