Help the hungry customer place his order at the sushi restaurant.

The waiter asks, "Are you ready to order, sir?" The customer replies, "Yes, _____ the spicy dragon roll, please."

The correct answer is I'll have.

When we make a spontaneous decision or order food and drinks at a restaurant, we use I'll have (I will have).

"I have" is used for general facts or possessions, not for placing an order!
