I went on the Brilliance last November on the 11-night Western Caribbean.
The ship is beautiful, very nautical.
Check out Portofino's at least one night. It's well worth the money. I didn't go to Chops but I'm sure that is such as good.
Best kept secreat....the Seaview Cafe in the aft Deck 12 is great for lunch instead of the Windjammer. It has sandwiches, salads, chili dogs, great onion rings etc. and great service. You can sit either in or outside. If you want to get away from the crowds, lunch is great there.
I wasn't very happy with the dining room food. The pasta dishes had very weird spices. Go to Portofino's for the best Italian food. I thought the Explorer had better dining room food. But maybe they've inproved it.
The Solarium pool area is great.
If you are into billiards, there are two self-leveling pool tables.
Linmor - Agree with Cathy about the Seaview, although we usually went late at night. I didn't find too much on the dinner menus some nights so needed a late night nosh. Food I did order from dining room was generally good, I got pasta much of the time. Windjammer is ok for lunch, but has alot of the same thing over & over so gets very boring by the end of 11 days. Have no personal experience with Portofino's or Chops but others at our table raved about them.
The pool was very crowded, especially on sea days. Chair hogging, etc. We ended up on upper decks to avoid the crowd. The Solarium pool was very relaxing and fewer chair hogs.
Other items - Ship has a great many activities (rock wall, mini-golf, cinema) that were underutilized. Lots of public space so the crowds were never felt except by the pool.
Suggest you browse through all reviews for this ship on this site plus CruiseCritic and CruiseAddicts. Each person will focus on different areas and give you a variety of opinions on all aspects of this ship.
PS - be sure to look for the fishermen outside the glass elevators - I think they're on the top deck on the sea-side. There are lots of clever added touches on this ship. You can spend a whole day just exploring.
