Our experience at Zulu Rooftop was nothing short of a masterclass in how to deter repeat customers. From the moment we attempted to book a table to the very second we left, it was an exercise in disappointment.Booking a table proved to be a displeasing experience in itself. After what felt like an eternity, we received a cryptic response to our query about heating options on their outdoor terrace: a single word, "agendada". Such brevity, such clarity. Upon arrival, we were graciously offered the only choice of sitting outside in the brisk 13-degree air (yes, there are rare chilly days in Paraguay). Heaters were present but, in a brilliant twist, were non-functional, the waitress said. The staff's solution? A plaid blanket, for which we were later charged 16,000 guarani— a delightful surprise we were not forewarned about. (We should have taken the plaids with us to dispose them in return). The pièce de résistance of our visit was the service, which was conveniently mediocre. Tips, already included in the bill, were a testament to their confidence in their own inadequacy. Our waitress, displaying impressive impatience, didn't bother to listen to our full order before retreating to the warmth inside, where a corporate event was clearly a higher priority than paying customers left to shiver outside. Despite our advanced booking, we were denied the apparent luxury of indoor seating, an act of sheer audacity and disrespect. Overall, the service could have been more attentive, the portions more generous, and the prices more reasonable. The only redeeming feature of Zulu Rooftop was the view, a small consolation in an otherwise regrettable dining experience.
