When I first got hired, I interviewed at one location and turned it down because I got bad vibes from the manager. I went to interview at another location and took the job there and no one said anything and it didn't seem to be an issue.
You usually have some time before you need to respond with your answer, so you should be okay to do the interview at the second location before giving an answer to the first.
