Thank you for sharing, Andrew1988!! It's a great font and pretty reasonably priced, too!

I have been searching for it as well!

The closest thing I've found is "Lemon Butter Display Font" by Marshall Taylor on Creative Market. It's less condensed and "intentionally imperfect."

Please let me know if you find out what font Subway is using. Thanks!
