Hi,
Please Let Me Know What Is The Difference Between At And In While Using Them Before The Name Of Place

Thank
Peter

.
Use at, Peter, when the place is considered or visualized as, or situated at, a point location (as when at long distance from the speaker):

I'll meet you at the drugstore.
I arrived at Denver at midnight because my flight was late.

Use in when the 3-dimensionality of the place is of concern or significance (as when specifying the inside rather than the outside):

I was supposed to meet her at the corner, but I found her in the drugstore.
I've never been in Denver before.
