We have the Kampa utility tent, and use it as our kitchen set up, its very good, stays dry in the rain and is of a perfect size for us to use as a kitchen, (2 adults, 2 young children) For us its ideal as the kids know not to go in that tent at all, which keeps them away from sharps and hot things.
The front opens fully which makes for a very nice environment to cook in. And yes before everyone pipes up saying you shouldn't cook in a tent, we do take full precautions with regards fire extinguishers etc. we had to weigh up the pros and cons and thought its safer to cook away from the children in a dry environment, than have them running around the stove at the side of the tent.
