The kitchen set is one of the more expensive loving family room sets to buy, which can be attributed to the light and sounds. The central oven display is a button that when pushed makes sounds of coffee brewing, water running, food cooking on the range, the oven timer beeping, and the phone ringing. However, the sounds are a little loud and it's a bit hard to distinguish between the coffee, water, and cooking sounds. The set comes with its own battery that is easy to change and is the standard AA size.
The dishwasher has a rack that can be 'slid' out when the dishwasher door is opened. We've found that it's pretty tricky to get it to move much at all. The coffee pot and cooking pot are attached to the countertop with a short tether. The oven door opens and the oven light goes on when it's opened. The oven timer also beeps whenever the oven door opens. The muffins/muffin pan that comes with the set fits on either the top or bottom rack of the oven. There is also a phone on a tether that snaps into a hanging cradle. My daughters (3 1/2 and 2) have no problem getting the phone off the cradle but don't have the dexterity of getting it back on yet.
The refrigerator has sliding vegetable bins, room for putting food on the shelves, and both a refrigerator and freezer compartment. Our girls like taking the included pizza out of the freezer and baking it in the oven.
There is also a purple rug, some food for the refrigerator (one molded piece), and a double high chair for the twins complete with a spoon (on a tether) and a bib for each. The bibs are relatively easy for little fingers to place around the babies necks, but it's a little tricky to get the babies into the high chairs. It takes some maneuvering and adjusting of the babies legs.
One of my favorite tie-ins is that the Twin Time Dollhouse with Bonus Set includes a "wet bar" with high-back chairs, towel, and tray with cocoa and cookies that match the kitchen set. This starts to make the room look like a real kitchen when you add a counter and chairs to eat at. There isn't a lot of room to get the combined pieces all into one space, but it fits decently on the extra fold-down floor space on the bottom central room in the twin time dollhouse (if you don't mind the chairs being on carpet).
Even though this was one of the more expensive sets, there was little hesitation in our buying it. First, what's a house without a kitchen? Second, my girls loved playing with the set even in the package at the store where they pressed the button repeatedly (you can always take out the battery, right?). Finally, the set has the perfect balance of detail and simplicity (just like the other room sets) to keep my girls interested and playing with it again and again.
