We'd seen tiny clips of this restaurant on a video ad for Europa Park. It looked like a fun place to visit. The idea is that you order your food and drinks on the touch screen, and then the food is delivered by small roller coasters.
It's a great idea, and the kids loved it. What's not so good is that you're in effect sat at large circular tables with other people. On the day we were there, and this isn't uncommon, the weather was incredibly hot, and with no air conditioning in the Food Loop restaurant, it was too uncomfortable. All the windows were open, but it was just too much, and we left earlier than we would have otherwise done.
Don't get me wrong, it's great fun to watch your order come flying through the skies towards your table, but the heat was just too much for us.
