I had my birthday celebration at Kost with 9 of my friends. I enjoyed the rooftop view however, the service was disappointing. The hostess was not so welcoming when we came in. We were repeatedly reminded that we only had our table until 9:00pm. It took a while to get our food. My girlfriend had to wait 30 mins for her appetizer while everyone else finished theirs. 3 of my friends were late so the lady asked if she can take away their seats. I did not appreciate that. We felt pressured to hurry outta there. I found it rude & unprofessional. Our server was fine. The food was nothing out of the ordinary & was quite expensive. This would be my first & likely last time here. Thanks for making my birthday special....
