餐廳訂左枱. 想同餐廳request window seat 英文應該點講？

Could you reserve a window table judged by my previous booking in advance ?

就像你說的：
May I request a window table.
當然更直接說(但聽起來便有點霸氣)：
I want to have a window table.

假如你已經訂了枱再想改的話，就要婉轉些：
Could you arrange a window table for me?

I want window seats with a view.
