We have been going to Singer Island for several years. I agree with many others' comments, and here are some of my observations.
Carmine's La Trattoria
This has been one of our favorites. The food has usally been excellent, although service is inconsistent. Although I don't usually eat steak when dining out, their filet (9oz) is excellent and a great value at $28 including sides and salad. I think the restaurant has become too big of an operation and the seafood and overall quality is not as consistent as it has been in the past.
Ruth Criss
We ate here for the first time (in this area) recently to use our Marriott dollars. Although the food is excellent, I find them to be over priced and everything is extra. Our service was just ok. Nobody refilled our water glasses (which IMO is a key indicator of service).
Bonefish Grill
Although this is a chain, we have had our best and most consistent meals here over the past five years. The seafood is excellent and fresh, great side dishes are included, and their tasty side salad is only about $3 with a meal. We have had carryouts here for the past few years so we can enjoy our meal with a good bottle of wine on our balcony. We usually order our food, shop at the adjacent Publix for a few groceries, and then pick it up and it is ready.
I agree that Sailfish Grill is now overpriced and food/service are inconsistent.
Max & Eddie's
We had enjoyed reasonably good meals here in the past, but their service declined a few years ago. Their NY style pizza was very good for carryout. The last time we picked up a pizza (2 yr. ago) the place was empty, so we haven't gone back. The owner appeared to be having issues keeping good help. I noticed the ratings have improved recently, but we did not try it on our recent visit. It is very convenient to the resort, so I hope it returns to its previous quality.
I have heard many good things about Jetty's, so we plan to eat there on a future visit.
With two adult daughters and recent job change due to corporate downsizing, our budgets require that we manage our dining budget. I also have a pet peeve regarding wine prices at restaurants. We enjoy wine with a good meal, but wine prices have gotten out of control. $9 for a 4-5 oz. pour of a bottle that retails for $9 is exhorbitant. I prefer to buy my wine at Costco or Total Wine and getting a carryout to enjoy at the villa.
We previously preferred local restaurants for fresh seafood, but few restaurants now serve fish locally caught. The seafood from Bonefish has been better than from other area restaurants we have tried.
