Nice photos! I missed Lviv. I have been to Lviv 4 times and I enjoyed there. I ate one of the best meat in my life in Basilico Restaurant. I drank one of the best coffee in my life which is called 'Lviv Rainy Day Coffee'. And also chocolates from Chocolate Factory are amazing.
Old men who play chess next to opera building impressed me! I played chess with them and I had great time. Next time please take a picture of them.
