Opening on the 9th of November Topaz is one of the few high-end restaurants of Istanbul with a breathtaking view from Gumussuyu, looking at Bosphorus and the Dolmabahçe Palace.

The corporate image consultancy of Topaz, was designed by Koray Ozgen who applied his distinct style, of using the visual aspects of the stone facets in an impressive manner within the interior.

Asteroid Lamps, designed for Innermost by Koray Ozgen, are featured in clusters round the bar area. Asteroid is a multi-positional lamp with a choice of facets on which to rest, giving each lamp the illusion of being unique and individual.
