Prepositions and Places
When English speakers refer to a place, we use in for the largest or most general places. You can say that “FLUENTRUSSIA is located in Moscow” And “for the best food, try the restaurants in Chinatown.”
For more specific places, like certain streets, we use the preposition on.
Example: There is bar on Grand Avenue in St. Paul.
Finally, we get to the most specific places. For exact addresses or intersections, we use the preposition at. If I invited you to visit us here at out place, I would say, “Come to my office at 330 Independence Avenue.” To be exact, it’s at the corner of Independence and 3rd Street.”
