I visited Sonata several times after its opening. Previous review 5 stars.
On my last visit last week, I ordered the Kepta Duona, Really delicious! however, I ordered the beef Stroganoff was not that great.. (I had it before when the restaurant just opened it was delicious). This time around, the beef stroganoff seemed like a different dish (the meat texture was not the same), did you change chefs/ cooks?
Anyways, the restaurant is unique, and live music makes it a good place for a dinner.
