How to say "Let's have a quick chat" in an informal environment, e.g. among
colleagues?

The emphasis is on the usage "chat", i.e. it's not "Let's have a discussion",
or "Let's have a meeting". It's "Let's have a chat" as the word is used in
English.

How to say "Let's have a quick chat"?
I believe you would say

> 「ちょっと/少しの）お話がありますけど、（いいですか）？

I have seen that in books (not manga) where the character wants to talk
briefly with someone and they say that.

If you were trying to say person A wants to chat quickly with person B they
could say

> "AさんはBさんにお話しがある"

Hope that helps!

When I casually _talk about_ chatting with friends, I usually express that
thought as:

> 「友達【ともだち】と話【はな】しをする。」 "(I) talk to (my) friend(s)."

「話」more closely means "talk" rather than "chat", but it does not imply a
formal kind of conversation.

So I would express "let's talk" by ending using 「ましょう」. A common construction
using this is:

> 「食【た】べましょう！」 "Let's eat!"
>
> 「話【はな】しましょう！」 "Let's talk!"

As @Chocolate states in the comment above, native speakers would often **not**
even explicitly mention "having a chat" when all we want is a casual chat.

We often say:

・「ちょっといい？」

・「ちょっといい + かな/ですか？」

・「（ほんの）ちょっと時間{じかん}くれる？」

・「（今{いま}）少{すこ}し時間 + くれる/もらえる？」

Each one is uttered with a rising intonation at the end and everyone will
understand that you would like a quick chat.
