Kaslik has got to be one of my favourite hangouts in London. The ambience is good (bellydancing on occasion), the food is amazing and they serve a wide variety of drinks including Lebanese wine and Arak. Highly recommended are the mezzes selections and the mixed grill.
It is also a great place to unwind and smoke a shisha. The staff are always happy to replace coals and look after their guests well. It can get busy so book in advance or be prepared to be seated in close proxmity on the cushioned couches!
