No symptoms, but because I plan on visiting my 96-year old mom in NC soon, I went to the former St. John's Villa school in South Beach yesterday. (Results in a couple of days.) Went about 11:00 a.m. and I was the ONLY one there being tested. Don't even ask for insurance info (which is good, because I don't have any yet).
Other sites around the borough also run by NYC Health and Hospitals at the bottom of this page:

All of them are walk-in, no appointment.
