1. Aer: So far one of the best places in Mumbai I have visited. No trip to Mumbai can complete without a visit to AER which is a luxury open end rooftop bar. You should ideally reach here by 7:30 pm to enjoy the perfect atmosphere. The bar does not serve alcohol but has a wide array of delicacies to choose from. It is considered as one of the most romantic restaurants in Mumbai. If you are planning to pop "the" question, this is the place to do it.
