注文は何にいたしますか？(レストランで)って英語でなんて言うの？

When in the right context, for example, when ordering at a restaurant, if you were to ask the person, "What can I get you?" it is assumed you are asking what food you would like. The same would apply to "What would you like?" When a person is waiting to order and are asked "What would you like?", they know you are talking about what food they would like to order.

Sometimes, customers take a while to decide what they want to order so it is probably a good idea to first ask them if they are ready to order. Then, the word "would" is the most polite to ask a customer what they want. I hope that this helps. :)

What can I get you? - The waiter is the person who gets customers things from the kitchen and brings them to the customers so the waiter can ask what he/she can get the customer. What would you like to order? - this is probably the most common way of asking what someone wants to order for their meal as it is very direct. What would you like to have? - customers have meals at restaurants and it is the waiter's job to get those things for them so the waiter can ask what the customer would like to have.

There are a number of ways you can ask a customer at a restaurant what he/she would like to order. You may include the word 'order' in your question or choose to exclude it. Because the customer is at the restaurant to eat, he/she knows that in order to have food on his/her table, he/she has to place an order. To show politeness and respect to the customer, as is always required in restaurants, you may end your question with 'Sir/Mam'. You can end with 'Sir' if your customer is male, or 'Mam' (short for madam), if your customer is female. So, you may ask your customer as follows: What would you like to have, Sir/Mam? or How can I help you, Sir/Mam? or Are you ready to order, Sir/Mam?

When you want to ask a customer what they would like to order (food/drinks); then you may ask in the following ways: -What would you like to order? -What would you like to drink and eat? -Can I get you anything to drink? And what can we get you to eat?

Good evening or Good afternoon - it is always polite to welcome customers with a greeting before taking orders. Referring to a man as "sir" or a woman as "ma'am" is respectful especially when speaking with customers. "Would you like to order something to drink," when arriving at a restaurant people normally start by ordering drinks before placing orders for starters, the main meal and dessert. An order for the main meal usually includes an order for a side dish like a salad or vegetables. "Are you ready to place your order?" can be said instead of "May I take your order?" A customer would usually respond by placing their order or requesting for some time to decide.
