There is, but it doesn't restore those particular cuts. Which is a shame, because the dinner scene is one of the worst edited in the movie, choppy and all over the place. You can literally see where dialogue has been chopped out.
For the record, the full scene was thus:
GORKON
I give you a toast: the undiscovered country. The future.
SPOCK
HAMLET, act three, scene one.
GORKON
You have never experienced Shakespeare until you have read him in the original Klingon.
CHANG
"To be or not to be, that is the question" which preoccupies our people, Captain Kirk. We need BREATHING room...
KIRK
I beg your pardon?
KERLA
Captain Kirk, I thought Romulan ale was illegal.
KIRK
One of the advantages of being a thousand light years from Federation headquarters.
BONES
To you, Chancellor Gorkon: one of the architects of our future.
SCOTTY
Perhaps we are looking at something of that future here.
AZETBUR
Commander Spock, mindful of all your work behind the scenes, and despite the cordiality at this mess, I do not sense an acceptance of our people throughout your ship.
SPOCK
They're naturally wary, ma'am. We've been at war a long time.
UHURA
How do both sides overcome ingrained prejudice?
CHEKOV
Perhaps with a few small steps at a time. Like this one.
BONES
And perhaps with a large step or two. Like a peace treaty.
CHANG
Captain Kirk, are you willing to give up Starfleet?
SPOCK
(looks at Kirk)
I believe the Captain feels that Starfleet's mission has always been one of peace -
KIRK
(glares)
Far be it for me to dispute my first officer. Starfleet has always -
CHANG
Come now, Captain, this dinner is off the record: in space all warriors are cold warriors.
SCOTTY
We have never tried to --
KERLA
You hypocritically presume that your democratic system gives you a moral prerogative to force other cultures to conform to your politics.
BONES
That's not true...!
KERLA
No?
Uhura turns to the Klingon next to her - all tact.
UHURA
General, are YOU fond of Shakespeare?
He looks at her, his hands and mouth full of food. Ugh.
Chekov pursues -
CHEKOV
We do NOT impose democracy on others. We do believe that every planet has a sovereign claim to human rights.
AZETBUR
(spits)
"Human rights." Even the name is racist. The Federation is basically a "homo sapiens" only club...
CHANG
(amused)
Present company excepted, to be sure...
UHURA
Well, I suppose we're not perfect -
SCOTTY
(rising)
Don't let them put words in your mouth! I haven't served 30 years in the engine room of a starship to be accused of gunboat diplomacy!
KERLA
In any case, we know where this is leading: the annihilation of our culture. Klingons will replace those on the lowest rung of the Federation employment ladder, taking menial jobs and performing them for lower pay...
CHEKOV
That's economics, not racism -
UHURA
But you have to admit it adds up to the same thing.
BONES
Don't be naive, Commander -!
UHURA
Who you calling naive -?
Kirk stares sullenly down the table throughout this.
CHEKOV
We're explorers not diplomats!
BONES
Starfleet's killed an awful lot of natural phenomena in the name of "exploration"...
SCOTTY
We follow orders...
CHEKOV
Since when has THAT been an excuse? Diplomacy must resolve these -
SCOTTY
Right - leave it to the politicians to muck it up and leave us defenseless...!
A COUGH interrupts the fight. All eyes on Gorkon.
The Klingons conceal their amusement.
GORKON
(finally)
Well. I see we have a long way to go.
Reactions from Kirk and his officers.
