When referring to a place in a city would you use In or At?

Both "in" and "at" can be used to refer to places in a city, but they convey slightly different meanings. "In" is typically used for enclosed spaces or specific areas, such as "in the park" or "in the downtown." In contrast, "at" is used for more specific points or locations, like "at the corner of Main Street" or "at the museum." The choice depends on the context and the level of specificity you want to convey.
