Service is sloooooow on the rooftop. We sat down right away and waited about 20 minutes for someone to even acknowledge we existed. There were easily 5 other empty tables and plenty of employees. I noticed them because they all looked like they hated their lives. We were just about to get up and leave when we someone finally said and I quote "What do you want to drink?". No hi, sorry for walking by 20 times and acting like you had the plague, nothing. The only reason I'm adding a star is because the drinks were cheap.
