What if you could only eat from one restaurant?

What if for the rest of your life you could only eat at one restaurant for the rest of your life. Nothing else but that restaurant for every meal of the day. It can be any restaurant even if it’s one that is no longer around. You cannot gain weight you stay basically what you are now unless you’re working out than you can change that way. All items are available even discontinued items. What do you choose?

I think I would choose Cracker Barrel. They have a good variety and I can hang out in the gift shop!

Edit: the food is free. It is the only restaurant around for you so you don’t even know of other options. If you choose McDonald’s all you will see are McDonald’s.
