I haven't found anything for hints for this game but I have figured out that if you seat everyone at the same time put old men first they take longer to order their food and then the business people second and then the regular people they are a bit faster. Get their orders at the same time or there abouts and feed them by the time they are all eating you can stand at the podium and make everyone happy till you get the next bunch of people seated. It will help your chain score also because your doing so many actions at once.Im still going at getting my 3rd restaraunt im on the last level of that now just trying to pick up the pace some I am loosing at least one customer in line.
