If you disregard the effects of COVID-19 for a moment, here's my normal pattern:

Every Sunday, choose between the same two places to eat each time

Every Monday eat at the same place each time

Every Tuesday - Saturday choose between the same three places every day

So,

the hypothetical isn't hypothetical for me.

Eat the same food every day definitely! I’m a bit of a picky eater unfortunately

I've just remembered that I actually eat rice 365 days so I would choose to eat the same food everyday.

Never eat the same food twice!

I would rather eat the same food every day, and I would like it to be chocolate.
