Best starship bridge?
My favorite is our own Starlancer's Yamato (you get to see it whenever Mukai rewards or reprimands you). It combines beauty and grandeur with safety and practicability - when in action stations, the captain's command chair and other bridge officers' can be lowered and embedded into the floor into crash cages, minimizing casualties in case of breach - one hole on the bridge won't kill everyone inside, just a select unlucky few. At all other times, the chairs and stations resurface and assume a more traditional ship bridge config, allowing the crew to walk around. Very, very beautiful and functional design.
My second best is Honorverse ships - this is the most military-realistic universe in the entire spectrum of sci-fi. Bridges also have crash cages, although not total embedding. Bigger ships have secondary bridges where the XO and a secondary bridge crew stand by to take over whenever the Captain is killed, his bridge destroyed or just comm dead. Plus the CIC, which can function as tertiary bridge if the others are out of action. Flag ships also have flag bridges for the commodores and admirals to concentrate on more strategic aspects of combat. All this redundancy thinking is very convincing. Plus, they make everyone wear skinsuits on beating to quarters.
My third is the SeaQuest bridge - just because they have a fish tank on it!
And the (new series) Battlestar Galactica bridge deserves the honorable mention.
