Considering switching doctors, looking for a walk-in clinic in Woodbridge/Amboy/Metuchen. I like walk-ins because they often have extended hours, and of course not having to wait for an appointment (and then wait some more when I get there) is a BIG plus. Would be great If they also had an on-site lab. The current walk-in I go to is great except that it's about a half hour from my house. Can anyone recommend a good place that's more local?
