Just went for a drink at the rooftop terrace. Was very disappointed with the service. As we were given a place to sit by one of the staff. Did not get any follow up service. No waiter came by to take our order. But instead after waiting 20minutes for a waiter to come by.o one did. Not to take our order but to instruct me and my group, that we could not sit there, and not providing any other solution. Following this interaction, while we waited to be reseated, we still waited with no service. Very disappointing experience, for a it's location and prestige. Will not be back.
