We haven't tried Alfredo's...yet. But we've taken our 3 kids to Coral Reef twice, and it was great both times. We had a party of 7 the 2nd time, so sat near the back, but the kids could still watch the aquarium, and had fun spotting the turtles, sharks, and rays. We've had excellent service there too.
The first time DH had grilled tuna that was out of this world! My shrimp pasta was good - it was shrimp pasta! Anyway, we HAD to go back and have tuna again, only I didn't realize it was only on the dinner menu!
Our server was SO great - went and asked the chef if we could have the tuna anyway, we were so disappointed - and we got it! Of course, it wasn't as good as the first time, but we appreciated the effort and it was still good.
My DD5 did OK with the food, but she wasn't that hungry and really just wanted us to leave her alone so she could color and look at the tank. She ate mac & cheese. The CM allowed my son to sub salmon in for the kids' fish, and he also tried the fish chowder (it was very good, I just couldn't get over that he ordered it!) They were very friendly there, and another CM (that brought our apps) talked to my kids about their pins and gave them a tip about HM pins.
If you go, don't miss the Chocolate Wave - it's as good as everyone says. But also don't overlook the Creme Brulee - it was also wonderful (and I thought my DM was daffy to order that instead of the Wave, but she LOVED it).
Enjoy!
