I assume that you are picking up the check for the restaurant. My 2 cents, visit with your guests and keep it simple. Games in a restaurant? That could be annoying to surrounding tables unless you have a private room. Plus, you are taking up table space and time. Please be generous in tipping the waitstaff. You are, in a sense, renting their space. I, personally, hate games. But I have endured too many showers over the years. I prefer to visit and enjoy the company of my guests. I never expect a "party favor" but I don't want any more stuff. I don't even care about attendance prizes at Guild unless it is a good one!
