I've been travelling the island in search of this elusive sea urchin pasta for a couple of days. Only to find it in a restaurant only half a mile away from my hotel. That's karma.
The entrance to this restaurant is a bit hard to find, but once inside is large and lively. Maybe a bit on the dark side (not Star Wars, in mean the lights), makes it difficult to take good photos, and to see exactly all the details on the plate.
I did enjoy the sea urchin pasta very much and the lobster ravioli was great as well, made with white lobster meat (unlike the other dish tried somewhere else that was also something else).
Good service as well, moderate prices.
