heh, it's fun how two different people can see the same thing and feel completely differently about it. I guess that's why it's nice to have lots of choices! I'd say that the Sunset Bar and Eden were tied for our favorite places on the ship. We liked the quiet and the intimacy of the Sunset Bar, and thought that Eden was the perfect place to relax (usually far more mellow than the other venues). In fact, we just sailed the Beyond and were disappointed that they expanded the Sunset bar to the point where it kind of lost its charm. (I'm sure most people will see the expanded Sunset bar as a huge improvement though.)
We like it because it's quieter, but we're also not creatures of habit--being able to change things up on a long sailing is really nice, even if the menus are substantially the same. And, honestly, a lot of the restaurant-specific menu items have been some of our favorite dishes.
