I have been on all of the Silversea classes and I have to say that I really like the food options on the new Silver Spirit.
The restaurant on the smaller ships was OK, but a bit stiff for a luxury line. But the Star Supper Club has a lot of tapas-like options that remind me a little of what Celebrity is doing with QSine on Eclipse.
It is kind of a wacky new way to look at food - different ways to serve and unusual tastes. It's a cool thing, I like it.
