We just went to the one in Atlanta yesterday. I noticed that there are many more items in the store than the catalog. All things I had seen before though.
I would suggest familiarizing yourself with all of the offerings before you arrive and give your daughter an idea of what you will be willing to spend. I paid for either hair or earrings for our dolls at the salon and our lunch. Hair is $15 to $25, and earrings were around $15 with a pack of 6 to take home. Anything extra came out of the girls' Christmas gift money from family.
The website is really helpful if you link through to the store. Atlanta gets very busy, especially this time of year. So I was sure to make a lunch reservation online. They also serve breakfast and afternoon tea in Atlanta. We were sure to arrive early because I had heard that the doll salon is first come first serve and can be a long wait. Luckily it was a slow day. We were able to be served immediately, but she was writing down reservation times for each family as they walked up. Also, there is a free personal shopping service by reservation. We did not really need that, but I can see if you are spending a lot or have limited capacity to carry things it might be really nice, especially on a busy day. We made all of our purchases, took the dolls to the salon, and then stowed everything in our car except the dolls and returned for lunch.
The Atlanta restaurant is a 50's diner/soda shop all decorated in pinks and silver/gray. Pink flowers on the table, pink doll chairs, and little plastic cup and saucer for each doll. Pricing in Atlanta is $15 for lunch (includes an appetizer and entree) for all ages 5 and over. The food presentation is really cute and kid friendly but the quality was good enough that we were able to have fresh salads, Asian chicken salad, etc. Salmon was even on the menu. I chose spinach artichoke dip with pitas and the Asian chicken salad. DD(7) chose green salad served with a veggie/cheese skewer and ranch and tic-tac-toe pizza served with fruit. Drinks and dessert were extra. I did notice that all of the portions were large except the desserts. The kiddie oriented desserts were cutesie and kid-sized, but the milkshakes and sundaes were HUGE! We had chocolate mousse in a flower pot and mini ice cream cones with sprinkles, each about $5. The "Bitty" meal for ages 4 and under is a separate menu. A Bitty meal with drink and mini-sundae included was $7.50. My daughter chose the chicken tenders (2) with veggie sticks and fruit. None of us finished our food, so I'd say the quality and portions are great. The pricing was a bit on the high side for the 7 year old.
We will definitely return, though probably not spending as much money next time.
Have fun!
