You will love to feed your hamsters using the Restaurant. The reason being: There is absolutely no need to open any doors at all. Two slots of differing sizes allow you to pour food into the Restaurant. You can also spin the restaurant's walls to allow your hamsters easier access to food.
The problem I had with the Sky Restaurant is the fact that my hamsters love to chew the floor of the restaurant. And believe me, my restaurant floor are holey contraptions... though they still cannot escape yet. It must have been a lot of fun for my hamsters - the biting and feeding within a first class eating establishment.
An alert: Food tends to be pushed out into the drain (or outer circumference) of the Restaurant. It's quite unsightly and the debris will fall on to the ground if you shake it. Also, because of this, you must carefully hold the Restaurant when it comes to cleaning it.
