Where are the best pies?

Just discovered this subreddit and my god is it a treasure mine. Had a quick look but there doesn't seem to be any good meat pies lately. So wondering what everyone's favourite pie is and where to get them? Are there any that open 24/7 like house of pies? are there some in odd locations or tucked away in the sprawling? strangest place you wouldnt expect there to be pie and they do it good?
