I usually would only snack two hours before and then eat meal after the business has concluded. But then I do mine from 10am or when places open and not last in line. And not at night. I don't want any surprises down there from other punters. Def do not eat take out or similar before hand. Don't down to many beers either before you go she can smell that. Other than that be well presented & clean, trim hairs a good idea. If you expect everything to be included head straight to a brothel. But do your research on AR reports before you head into a random shop or brothel. You don't want to turn up to a place where a granny is waiting for you behind a hanging sheet.
