Not an expensive minimarket, you can buy drinks, sweets, sunscreen, if necessary, personal care products and washing powders. In general, the usual minimarket for locals. It is better to take lira, because dollars are exchanged at a high exchange rate. We often went for ice cream, sweets and soda, cheaper than in tourist stalls.
A good Turkish shop, prices are normal, cola, sprite, fanta for 110 rubles, Turkish tea for 150 rubles, there are all the necessary products, even sun creams (cost about 700-800 rubles), the staff is polite to tourists
