I'm currently enjoying my travel in San Francisco. I went to Fisherman's Wharf with my friend today and there were quite a number of eateries. Since my friend lives there I asked if he knows any good place. I said "Do you know of any good place?"
Then I thought I could have said the same sentence without 'of' and still made the same sense. I don't know, maybe I shouldn't have used 'of' at all.
Are they all correct? if they all are, any difference?
Please let me know, thank you very much.
'of' isn't necessary.
EX: Do you know (of) any good places? (note, any + plural noun)
Glad to hear you're having a good time.
