It is always open on weekdays. There is an ATM. There is an exchange. You can always put money on the card. Friendly girls. Always a good rate from all the surrounding banks.
22.10 I wanted to withdraw Russian rubles, the cashier replied with a dissatisfied look that there was none (while packing the cash register). Of course, it was 10 minutes before closing, I didn't want to unpack everything back. When asked if there is an ATM, she answered if it was loaded. As it turned out, there are no ross rubles in the ATM at all, there is not even a tab that they can be withdrawn there.
