Help the hungry customer place his order after a moment of intense deliberation. Choose the correct phrase to complete the sentence.

Waiter: "Are you ready to order, sir?" Customer: "Yes, everything looks amazing, but I think ___ the spicy garlic noodles."

The correct answer is I'll have.

We use will (or the contraction 'll) to express a spontaneous decision made right at the moment of speaking. Ordering food at a restaurant is a classic example of this!
