3.5 stars for me. Okay, so it has pretty much anything you'd want (think super grocery store, like…read morea Superstore or Walmart in Canada). Toys, electronics, drugstore type things like shampoo and makeup, and of course, food. Oh, the food! Cheeses, meats, wine and spirits galore... A bit overwhelming really. That's where they lose points. I couldn't find a basket anywhere, things weren't marked well for pricing or even a name sometimes, you were on your own for bags (but nary a mention of this anywhere), and it's assumed you know to weigh and bag your produce before leaving that section. Ran into a lot of empty shelves and broken items on the floor, waiting to be cleaned up. Then, the lines! Took me 20 minutes to just get through to pay.
So... Yes it's great to get everything in one place (rare in France, I've found) but you pay for it in different ways.
