Hello!
We stopped for a snack, took 3 quesadillas and regular black tea.
2000 lire came out, an additional amount was included in the bill.the line when I asked the waiter what it meant was "tax." Then I found out on the Internet that this was a "service" that no one had warned me about.
He did not specify the cost of the tea and then saw its cost in the bill - 300 lire. As for me, this is the most expensive black tea in Istanbul.
