It is interesting simply as a historical landmark. It doesn't make sense to buy anything here: firstly, everything is much more expensive than in other places, and secondly, that's really all consumer goods. Maybe, of course, there are good things, but we didn't find them, we just didn't go around it because it's so big. What should be noted here is the best dollar and euro exchange rate against the lira, the best I have ever seen.
There are a lot of different shops for every taste and purse, accept any currency, sometimes even rubles. Many people are treated to free water, tea or coffee. Many people also understand Russian.
