I have always had great service at this store. Everyone has always been really friendly and I have had only great experiences.
Yes it is usually busy and really crowded, but you can make appointments on line by looking up the store on the internet and making a reservation.
They have lots of computers, laptops, iPods, gizmos and gadgets to check out and play with. The sales staff is really knowledgeable, friendly and helpful.
Granted I have only gone in here for repairs and to browse. I make my purchases from apple or online, it is a helluva lot cheaper. The sales staff was nice enough to point me in the right direction for service from Mac Media or purchases online.
Go check it out and enjoy.
