Question

Which expression should you use to tell the waiter what you would like to order at a restaurant brainly?

Answer 1

The expression you'd use to tell the waiter what you want to order is quisiera.
That word literally means - I would like, after which you would say what you would like to order. 
Le traigo means - I will bring you..., algo mas means - anything else?, and de nada means - you're welcome.
