Is there a post office around here? correct Is there any post offices around here? should be (Are there any post offices around here?

plural or singular is the same, the second seems to be correct, seems due aim not native,

Hi lambchop. Man, I haven't called anyone lambchop in years! And it was only when I wanted to... lol Are there any post offices around here? :P

saying "Are there any coffee shops around here? is better ( plural)

Would you use singlar or plural? Say if you are looking for a coffe shop or a good Italian restaurant.
