Choose the spot you want to dine in. If the weather's nice, enjoy your meal in the garden or on a private balcony—particularly if you'll have a good view of the sunset or a clear night sky. If it's too cold or wet for the outdoors, there are plenty of options for where to eat inside. Set a small table by the window, use cushions as seating around a coffee table by the fireplace, or sit side-by-side at the kitchen bar.
As for table dressings, stick to the classics: use nice dishes, cloth napkins, and cutlery for each course. Unsure how to fold the napkins or where to put the forks? A quick online search will bring up all sorts of resource videos to guide you step-by-step.
