Ozer, Langham Place, Regent Street has a nice outside terrace area, which would be good during the summer months to people watch while enjoying your meal. It is just opposite the Langham Hotel, and near the All Saints Church (straight down from Nike Town). Inside, the restaurant is warm and welcoming, and have good, friendly service. The hummus, olives and warm bread were a nice way to start the meal, especially after just walking in a torrential downpour. Nice Scottish Rib Eye Steak; only had a couple of grissly bits. My friend advised her moussaka was good also.
A must = Baklava for dessert.
