Pedir vs. ordenar
While both pedir and ordenar can be translated as "to order," they are not interchangeable. Pedir is the standard and most common choice for ordering food and drinks, implying a request. Ordenar is more formal and primarily means "to command" or "to organize," and using it for food can sound unnatural or overly authoritative.
Pedir
A1Pedir is the go-to verb for ordering in everyday situations, especially for food, drinks, or services. It translates best to "to ask for" or "to request," making it the polite and natural choice in a restaurant or when making a purchase.

(I am going to order a pizza for dinner.)

(Are you ready to order the food?)

Si necesitas algo, solo tienes que pedirlo.
(If you need anything, you just have to ask for it.)
Ordenar
A2Ordenar carries a stronger meaning of "to command," "to give an order," or "to put in order/organize." While it can be used for commercial orders (like a company buying supplies), it's far less common for food and can sound bossy or overly formal. Its primary uses are unrelated to ordering in a restaurant.

(The captain ordered the sailors to raise the sails.)

(I have to organize all the books on the shelf.)

(Please, help me sort the documents by date.)

Summary
In short, always use pedir when ordering food, drinks, or common services like a taxi; it is the natural and polite word for making a request. Reserve ordenar for its primary meanings: giving a command (like a general or a judge), or organizing things (like a room or files). While ordenar can be used for large, formal purchase orders, using it for a coffee will make you sound out of place.
