Walk in is fine but you may end up waiting for a space between people who made appointments. They're very efficient so even if you don't have an appointment it shouldn't take very long.
You can do either. Making an appointment is the best. If you decide to walk in, there's a comfortable waiting area.
Why spend your day waiting? Make an appointment at your convenience.
I would imagine making an appointment would be best.
It's best to have a appointment , that way you can schedule for your convenience plus , you have first choice menu of the day , if you do not have an appointment you will have to wait in the lobby for space to open up !
