We can go in all the major shops like Macy's, or in every area you have public ones and they are very clean. You have one close to the tea room and Starbucks, one close to the Amazon store. You can find signs everywhere to help you find it.
There's one on every block, just check the information signs or go to the major stores. I used the one beside Starbucks & also the one by Frost Gelato. Both were very clean & no waiting.
