We are visiting here for many years. The quality of the food, is always good. However - year after year, the service quality goes down. Tonight - very few table was taken. There is no reason to wait 15-20 minutes before anyone will approach to say "hello".
I is very ( very!) rare that we are not giving tip. Is services is not good - we give less - but we always tip.
Tonight - we didn't gave any - it was "just ignoring with no reason"
