My partner and i went here after being told about the place by an English guy on top of the Keri cliff!!
What an awesome restaurant, it's slightly more expensive than the one's in kalamaki town but well worth it, they only have around 15 items on the menu, as the waiter said, they keep it simple and perfect each dish.
We arrived there around 9pm on a saturday night and the place was empty, by 10 it was full of Greek people, i always say that if it's good for the locals then it sure is the place to be.
I had 'Chicken B on my mind' and my partner had another chicken dish, both amazingly cooked, i had rice with mine, she had crinkle cut home made fries which were lovely.
The toilets were by far the most impressive i have ever seen on the island.
Best meal of the holiday by far and will definately be going back to Gastro Nomi
I've been to Kalamaki 3 times now and have just returned again.
