There was one waiter plus the owner, and they who both introduced us to the cats while our food was being prepared. The whole restaurant was dark and candlelit so it was very atmospheric. The layout was also nice with a set-up of adjoining rooms and a private area the cats could retreat to.
The staff were fantastic, happy to tell us the stories of the individual cats but also discreet and giving us plenty of privacy to eat in the company of the cats. Even though they were close by they were really unobtrusive and it really felt like a special evening for the two of us.
