The Berney Arms would be good but not sure if would be back open
The Berney Arms has recently applied for a new license after being closed for five years, so I'd count that out for July.

Along the River Yare, most likely places for pubs to have reopened will be Reedham, Thorpe, and even Norwich, but I'd check by phone first.
Here is a map of pubs with moorings who may be glad to see you -

One other place came to mind close to Brundall, so perhaps for your first or last night was Brammerton Waters Edge. This has moorings and has been running a takeaway service, so even if it hasn't reopened you could get a decent meal. They have a mobile number on the website -
