Traditional Turkish coffee house - Rear of Mezzo Bar

Hi im new to this forum,

I have seen posters of an application that they are going to have a traditional Turkish Coffee House in the rear of Mezzo. Just to clarify this is not the smoking area in the rear of mezzo. Its the building next to this. ( Marble showroom).

This brings many concerns on how the access to this rear coffee house will be, the rear of that buidling is used for parking by the estate agents and mezzo bar staff. The rear has gates which close @ 6.

Mezzo bar is family oriented and having a social  Turkish mans club will defiantly affect the atmosphere. Im Turkish my self.

This is what it says on the Harringey website :
