My family and I have been with att and this store for years and every time we upgrade or visit, we get the best service. It also helps that the workers here speak mandarin, Cantonese, and I think Spanish too? They have all the att phones plus cases, chargers, screen protectors etc. All the workers are very knowledgeable and know the software and hardware of all the phones so don't be afraid to ask. Only bad part is the parking lot which is very narrow and is actually a one-way.
