Sounds like you are having a great time! We have been on Equinox 6 times, with a B2B scheduled in September. I have to eat gluten free, too. I’m surprised you enjoyed the pizza as the last time I had it, it was terrible and last cruise I did not try it. I will give it another chance! The pasta, sauce and meatballs are very good! Also, go to the Spa Cafe for some gluten free breakfast/lunch choices and their GF Apple Cookies are good. Last two cruises the gf cakes were horrible - like a wet sponge cake. I have always eaten the gelato but last cruise I was told none of them are gluten free. I could not get an official answer so I stayed away from it.
Enjoy your cruise!
