I am a freelancer who has a pretty obscure health insurance company that usually doesn't cover much -- just emergencies. But Union Square Urgent Medical Care actually accepted my insurance. They are open late on weekdays - to 9 pm - which works out well for those who can't make it during normal business hours. I came at around 8:30 PM and they were able to see me right away. I literally filled out my paperwork and was able to be seen right away. The service was fantastic, the medical practitioners were extremely helpful, and overall I had a great experience. Will definitely come back for future visits, and I am extremely happy to have found this walk-in clinic.
