I know its not what you're really asking but you're best bet for a 'special' meal will be to travel a short distance to Palma, alternatively there's a 2 Michelin starred restaurant in Puerto Portals not too far from you called Restaurant Tristran.

"Awarded two Michelin stars, this restaurant is one of the best places to eat in Mallorca offering creative, sophisticated and elaborate cuisine. The restaurant has been featured in many guides and is a place for gourmets and connoisseurs. It has a large terrace overlooking Puerto Portal in Calvia, and is a popular place for the yachtsmen and rich and famous glitterati visiting the island"

Hi, I would recommend Le Petit Bistro for a speceial meal. We ate there a couple of years back and the food was fantastic.
