Yes, I've been there 3x in the past month for different things as a walk in and was able to be every time. Shortest wait was about 15 minutes and longest wait almost an hour personally but it all depends on how many walk in and appointments are waiting ahead of you and they do not guarantee you will be seen before closing time.
They were on the day I went but it's vital to get there early.
