Back to report on last evening.....discussed it in the way to dinner.

At coco maya, it was clearly shown at the bottom of the menu a service fee of 15% is added. We added additional tip to bring it to 20%. (I underestimate our projected dinner cost by $9)

Btw - we all loved our food. We probably sampled 80% of the menu.

NC sailor - we always tip on gross at home in the states but we generally don't order expensive wines by the bottle.
