What do the mean of ” just another talking shop” ?

Hi,

"Just another talking shop"
" talking shop" is a pejorative term that is used to talk about some
unproductive or bureaucratic organizations mainly.

In daily life, if someone says this to you, it just means it is of no use, empty
talk and he or she doesn't agree with what you have said.
