LOVE Aqua class! I wish they would open Blu for lunch, especially on embarkation day.
Anyway, the selections are limited, but, having to eat gluten-free, I usually head to the Aqua Spa Cafe, which is open to all.
They have healthy, small plates, and from my experience, they are always plated by the staff (last cruise 2018 but going again soon). They also have cookies, muffins, soups, smoothies, and more. Not everything is gluten-free, so it's great for everyone who wants lighter offerings. And if you're super hungry, just eat more! 😄
I like how they keep the food separated for safety.
