It was very easy to put together- it took my husband and I about 1.5 hours to put it together...this included putting all of the stickers on and setting up the food items that come along with it. When my daughter saw it Christmas morning so said "Whoa!" about 50 times. She ran to the kitchen and was so excited about all of the gadgets and accessories.
The phone and microwave both make different noises when you press the keys. Also, the stove recognizes the pot that you put on the burner and makes corresponding noises (sizzling, boiling, etc.) It comes with 2 plates, bowls, cups and cutlery sets as well as two baskets full of food. Some of the foods is more realistic looking than others but to me that is a minor detail.
The set has a counter so that you can sit on the enclosed stool and eat. Two smaller children can play comfortably in this kitchen. I think that the kitchen is plenty big enough for a child up to age 4 or 5 and hope that my daughter will not outgrow it before then.
