Look me up when you're in town

Look me up when you're in town.

When you next come to my town, try to find me (and we will get together). (A vague and perhaps insincere invitation.) Bob: Nice to see you, Tom. Bye now. Tom: Yes, indeed. Look me up when you're in town. Bye. Sally (on the phone): Bye. Nice talking to you. Mary: Bye, Sally. Sorry we can't talk more. Look me up when you're in town.
