Reception Venue near Woolwich Town Hall (25ish people)

Hi all, we are toying with the idea of a micro wedding which would be 25 of our immediate family. Most of them live in Kent and so can easily travel to South London - because of this Woolwich Town Hall has caught our eye venue wise.

The thing is we live in the North and don’t know the area well - can anyone suggest a suitable venue for the reception afterwards? Thinking we would have a sit down meal, preferably in a private room of a pub or restaurant and then maybe a few drinks afterwards?

Any suggestions in the area are welcome! We also aren’t against hiring transport to get all our guests to a venue if driving is required, thanks! ☺️
