Do you take walk ins?

Yes, they do take walk ins

Yes, they take walk ins. Might be a little wait if no appointment. We had to go in late one night and waited over 5 hours. Might be better off to stay at home and make an appointment.

They are open 24x7. It is a super idea to call ahead though, just to let them know what's coming in.

Yes
