We ordered food through the app.The order was accepted, the courier arrived, and the establishment is closed. Why is there a 24/7 signboard then? They don't take the phone. In Yandex and in the app, then change the opening hours, since you don't work at night. It's a terrible place.
Regarding burgers, they are cheaper than in other establishments, but their taste and appearance depend on which shift you are on, they can be juicy and tasty, as well as dry burnt and raw. Regarding doners, I do not advise at all there are a lot of places where you can order more and tastier for a lower price)
