Quality clothes for fair prices, clean store, nice staff, and great checkout experience.
I came here to buy some stuff and the prices were similar to stores like Old Navy or Macy's. They also do alterations if you need it. The self-checkout machines are fantastic. If you haven't used one before, just throw everything you want into the machine and it'll give you the total within seconds, without any barcode scanning needed. The staff members helped me find something and they were very nice. I visited in the evening and even then, there was a short wait in line, so there are probably really long lines at some points during the day like what other reviewers were talking about.
I highly recommend visiting Uniqlo if you haven't because the clothes are good quality and will last and the prices are comparable to other stores. This is currently the only location in SF since the downtown store closed a few years ago.
