We went to Nikki Beach for a late lunch and I have to say I did enjoy it. We had a lovely table right by the beach - the great thing about this place is that you can take a dip in the bay and go back to your table, no one was rushing us to leave. I see some negative comments about the service but we had no problems - the service was prompt and they were attentive enough (that being said we were here during low season). I had a sushi platter and I thought the fish was quite tasty but this being St-Barts you do tend to pay quite a bit for what you get. My friends liked their meals as well but felt they were average.
Overall I would come here again if only because of the relaxing atmosphere, it really is a nice way to spend a few hours in the afternoon.
