Hi! I remember your mom and sister very well. We had a nice long chat about being vegan. We did not have enough avocado maki rolls for your sister because it was a very long (10-day) national holiday in Turkey and it was impossible for us to find avocados as the stores and market house were closed. We explained this to your family. We apologised and served your sister extra sushi on-the-house to make up for any inconvenience. I also remember your mom, sister and their friend leaving here very happily. They even said that they were very happy because this was the first satisfying decent meal they'd ever had in a few days during their stay in Istanbul.
