Normally, going out to a nice dinner is saved for special occasions. Instead of going out, why not stay in and make any occasion special? No reservations needed.
Create your own pop-up restaurant and have a fine dining experience without leaving your own kitchen. Before dinner, assign jobs—waiter, head chef, prep cook, etc. Create a small menu on a piece of paper.
Take it up a notch by lighting candles and having everyone dress up! Make sure that your little servers keep the table stocked with water and bread leading up to the appetizer course. You can even have someone play food critic and give a review of the meal.
