I would be trying to encourage chanting of pedophile.

Thanks for the correction! The site I was using was a site for English speakers considering moving to Turkey. It was difficult to verify with my lacking language skills.

The 850₺ was the average cost I could find while poking about restaurant listing in Istanbul so I was likely getting touristy places. It was very difficult to find a place with prices on their recent menu photos or websites as well. I suspect the places I was finding were more upscale/touristy than local.

The images of menus from ~3 years ago have prices that line up with the average monthly wages. The recent photos of menus have the prices blanked out.

The “new” price of ~850 TRY for a single serving is over 25% of the average monthly wages (2900-3200). The site providing wages doesn’t specify if that’s the average earnings before or after tax either. Prices on older menus are more like ~50 TRY for the same item.
