I think we've had tables at every level and honestly the views are about the same if not better the higher up your are, IMHO. Its nice to be against the glass, but we've had large groups (13) in a booth on the first floor -across from the glass. The lobster bisque is trypically very good - have had a few occasions when it was bland, but our last time there it was nice. I usually get the beef entree as I'm not much of a seafood fan, but dh and ds have generally enjoyed their fish entrees.
We've had a wide variety of service there - from excellent to not leaving a tip bad. I haven't seen as many consistent servers there as some of the other places. We've had some servers at Artist Point and CA Grill that have been there for years - haven't seen as much of that at CR. Generally they're pretty slow, but they don't rush you either.
CR isn't a must do to me, but its always a good back up
