Zhù nǐ měi tiān dōu kāixīn.
I hope every day is a happy one for you.
祝 goes first, followed by the person and then what you wish them: 祝你生日快乐, 祝你身体健康, 祝你一路平安. The verb does not translate on its own, and it is never used about yourself. Without it, a bare 生日快乐 is still correct and is said constantly, like a "happy birthday" called out in passing.
On your birthday you eat a bowl of 长寿面: a single noodle, as long as possible, which is neither cut nor bitten through while you eat it. The length of the strand is the length of the life you are being wished. The custom is old and very much alive, and the birthday cake with candles, being newer, has not replaced it.
快吃吧 means "do eat, it will go cold". 快 in front of the verb hurries things along, 吧 at the end takes away whatever the order might have had that was curt. Without 吧, 快吃 is a command; with it, an invitation. You hear 快走吧 and 快看吧 in the same way.
