Why do we use "At" the City Plaza not "in&quo

Could any teachers explain why we use the prep "at" before Plaza as in:

There was a fun fair at the City Plaza yesterday.

Thanks a million for helping again, teachers! Sorry for the hassle!

It's just a guess, but perhaps we say

• at the plaza

because it is a place you go to. Example sentence:

• When I saw Richard he was standing on the sidewalk in front of a shop at the plaza.

:)

Thanks again, teacher Ronbee! ^o^

At is often used for general locations, so a plaza, which is normally a large place, takes it. \^_^/

Thanks for your advice too, teacher Tdol! ^o^

Any time.

How about "at the lobby"? Lobby is also a general location and a large place. Is using "at" correct? or i should use "in the lobby" instead?

ex: We'll meet you at the lobby. or We'll meet you in the lobby.

thanks!

I'd use 'in the lobby', but I have heard 'at' used as well. It's not always clearcut.
