Hi. Thanks to everyone who gave me input leading up to my trip last week. Just got back last night, and here's my full report.
Overall, the dining on this island is fantastic, albeit expensive for the most part.
Our favorite spot was The Straw Hat. It's fairly casual and right on the water. My standout dish was a special of swordfish in a lemon beurre blanc, served with garlic mashed potatoes. We also had crab spring rolls to start, which were delicious, though a little greasy (as most spring rolls are).
Our next favorite was probably Altamer. The setting is stunning--also on the water, but very dramatically lit and decorated. Here I had a fish soup to start, followed by a delicious grilled lobster. My husband had their signature tomato tart (which was better than my soup), and a trio of fish: snapper in a saffron sauce, pistachio crusted grouper, and a third fish I can't recall. The restaurant had great service and attention to detail. It was probably the most expensive of the restaurants we ate in--and the fanciest, though not "stuffy" at all.
Scilly Cay was a terrific experience. Only open for lunch, you drive to a spot near the dock and their boat comes to ferry you to the restaurant. We had THE most delicious lobsters. My husband also proclaimed this the place on the island with the best rum punch (and he sample quite a few).
Mango's was also enjoyable. I had my inaugural taste of crayfish (here prepared in a lime/coconut curry) and loved everything about it. Their lobster cakes (an appetizer) were also wonderful. And my husband RAVED about his sesame snapper. We found the atmosphere to be somewhat lacking, possibly because there was a busload of thirty that was dining at the restaurant on the night we were there. But maybe I was just bitter that they were occupying all the waterfront tables....
We stayed at Cap Juluca, and since we had some meals there as part of our package, we got to sample all of the resort's restaurants. George's for lunch was a no-brainer. Recommendations there include the gaspacho with lobster, Caesar with grilled shrimp, tuna burger, and tequila/lime marinated shrimp. We dined there as well for their famous Friday night BBQ; my recommendation would be to skip it unless you're staying at the hotel and have some meals included in your rate. Otherwise, you could do better for the money elsewhere, unless you're a really big eater and like to take advantage of all-you-can-eat events. Kemia would probably be my top choice at Cap Juluca, though others might prefer Pimms. We ate at Kemia twice, and found the top dishes to be the lobster nems, the crabcake with mussels in a curry sauce, the veggie samosas, and the sashimi served with sake. For dessert, Kemia's chocolate dominoes were yummy, as were the chocolate beignets. I ordered their peach parfait and had to send it back--it was truly inedible: peaches soaked in massive amounts of the most acidic vinegar. Pimms was a very lovely setting (nearly identical to that of Kemia, but more formal), and the service was great, but I can't remember what I ate there--that's the impression it made on me. Not that the food was bad--I definitely would remember that. But it wasn't anything memorable.
