I used to have a couple of different kitchens that the kids would never play with. My husband and I found this one sitting by the side of the road one morning with a "free" sign on it and we snapped it up: ghttp://www.toysrus.com/buy/kitchens/step2-50-s-diner-882100-3153188 by the
We've had it for at least a couple of years now and the kids love it! They've used it every single day since we got it. It was definitely well worth the embarrassment of getting out of the car and grabbing someone else's trash.
I'm not sure what made the difference to the kids other than maybe the attached seats? I have the same bins of play food, pots and pans, plates, etc that I had before but they do seem to like pretending to be waiters/waitresses and customers vs. just playing "house".
