This REWE grocery store was super convenient to our hotel (Ascot) in Cologne. It has everything you may need, including toiletries you may have forgotten if you're staying in a nearby hotel, and it is a full-service grocery store.
They even have a sushi counter and fresh foods available. Personally, I grabbed a TON of chocolate bars to take back to the US. Chocolate in general tastes so much better in Europe.
I love how German grocers have a display of fresh pastries at the front of the store. Each time we walked by the store, my husband and I had to stop in and grab a pastry.
The self-checkout was very convenient as well, and when I needed help, the staff were accommodating, especially as I know very little German. read more
