Hi Mackenzie,
You are a woman after my own heart! A casual date night at a World Showcase restaurant at Epcot sounds wonderful. Let me share a couple of my favorites with you.
My favorite restaurant in Epcot's World Showcase is
Chefs de France. The feeling of a bustling French brasserie is comforting, and the food is delicious. I like it there so much that it is where I had my birthday dinner last year! I especially love sitting in the side room near the bank of windows and just watching the people walk by as I eat. Another favorite for me is
Rose & Crown Pub & Dining Room. This is probably the most casual feeling of the restaurants that I am mentioning. I really enjoy the English fare along with a pint of beer. Finally, you could try
Le Cellier Steakhouse. This might be a little more upscale than you are looking for in a casual dinner, but the steak is absolutely delicious.
I hope that this gives you some thoughts for your date night out, Mackenzie. Have a wonderful time planning your vacation, and please do not hesitate to ask if you have any further questions.
