The Bored Monkey located in the heart of Narrabeen is a great way to spend a Friday or Saturday night, and includes live music while you eat. The restaurants atmosphere is industrial and high-end, and the food matches this. The tapas there is utterly amazing, and a good way to try out many different foods and share amongst your group of people. My favourite is the prosciutto-wrapped asparagus, the sauce on it is to die for. This place does get busy, especially on weekends so I would book in advance, and use public transport like the L90 as the car park is small and being renovated. Also means a great night for all with no designated driver!
