Sartoria is a relatively new Italian restaurant which has come up in the Priya Vasant Vihar complex and is situated near Nirula's.
First off, the good bit: the food, though expensive, is really good. We sampled Chicken Cannelloni, Spaghetti Bolognaise, Chicken Alfredo pizza and the Veg Lasagne - all of which were smashing. They have a drinks menu - though since we went there on a dry day - can't comment on that.
About the service: For us the service was decent - we needed to move to a smoking table and there wasn't one available. But since there was no-one in the vicinity of where we were seated, they were nice enough to let us smoke there.
Couple of gripes : The sofas were differently colored (read dirty) and the table cloth sported a couple of polka dots (read slightly dirty). Given it's an expensive restaurant - I wouln't expect that. Also, for some reason they only serve mineral water.
