However, today our restaurant has met its match!

Today, they arrived at the Magical Restaurant for a meal. The waiter said, "Welcome, three guests, please come in." The little boy, his dad, and mom then entered the restaurant and ate a kids' meal, a sandwich, and omurice. They kept exclaiming, "We're so full," but still wanted to eat more. What should they eat next?
"Ah! I want okonomiyaki!" So, they entered an okonomiyaki restaurant, where people were eating okonomiyaki with strange little spatulas.
After finishing, even though they were full, they still wanted to eat something else.
And so, they went from one restaurant to another, yet they still wanted to eat! What on earth was going on?
It turns out that there's only one place in the world where the food is the best! Do you know where this restaurant is?
