Waiter: "Good evening! Would you like to hear our daily specials, or are you ready to order?" Customer: "I think I'm ready. I'll have the truffle risotto, please." Waiter: "Excellent choice. And would you like some sparkling water with that?"

Use "Would you like...?" to make a polite offer or invite someone to do something. Do not use "Do you like...?", which asks about general preferences (e.g., "Do you like Italian food in general?").

Use "I'll have..." (I will have) when making a spontaneous decision or ordering food and drinks at a restaurant.
