Sure! Here's a polite way to ask for a table, order food, and request the bill in English:
Requesting a Table:
"Hello, I would like to request a table for [number of people], please."
Asking for the Menu:
"Could I see the menu, please?"
Placing an Order:
"I would like to order [dish name], please."
(You can specify multiple dishes if needed, for example: "I would like to order the grilled chicken and the garden salad, please.")
Asking for the Bill:
"Could I get the bill, please?"
or
"May I have the check, please?"
