Drinks for a post wedding party for our office colleagues and friends?

Oof- I wouldn't.

That's a lesser party for people who didn't rate high enough to be invited to the nice ne- and an obvious gift grab. In a word, tacky and in another word, ill advised in terms of your career.

It is a very tender issue when you have a B-list of people who did not get an invitation to the fancy event. You are putting them in a position of feeling they must produce a gift - even if you tell them not to, which is another faux pas.

Life should go on after you are married - to "celebrate" withthese other people is to basically bring them a doggy bag, and have them feel as though they still have to give you something for your wedding. The nicest thing you could do for them is to NOT do this at all. It may seem nice, but in fact its rude.

That list sounds sufficient for you and a lot of other people to ruin their careers by saying things they wouldn't without the alcohol. There's an old saying, "never mix business with pleasure". This could very easily be a big mistake.

I don't think any of the answers above deserves best answer.

Dude you don't throw a B-list party to try to extract gifts from your workmates. Give it a rest.
