Meaning of a quote in movie Casino Royale (2006)

Solution 1:

It's like saying, "There are men, and there are men."

It really depends on the context. But in this context, I reckon Vesper Lynd is really saying:

There are alright dinner jackets, and there are good dinner jackets; this is the latter...

"This is the latter" refers to the second of the dinner jackets, which I am presuming, is "good". (I haven't watched the movie)

It's just another way of saying about the difference between two things of the same type, but different quality.

Edit:

Quoting @Unreason:

To determine which one is better you have to provide more context. Specifically, if the sentence 'And I need you ... at that table.' is affirming the choice of the dinner jacket, then the second one is a better choice. If it is opposing then the second one is a worse choice.

Solution 2:

It means that there are ordinary, run-of-the mill dinner jackets, and then there are special, well-cut, expensive dinner jackets, of the sort that a millionaire, master criminal or international secret agent would wear.

The idiom can be used for other things too:

I've tried pizza and I don't really like it.

Ah, but there's pizza, and there's pizza. Don't write it off until you've tried pizza from Mario's...

Solution 3:

There are answers and then there are answers.

This is, in wider sense, a ploce : The repetition of a single word for rhetorical emphasis. The term is from Gk. plekein, "to plait". Also sp. ploche, ploke, conduplicatio, diaphora, doubler.

In this case, specifically, it could be:

1) Antanaclasis (from Gk. anti “against or back,” ana “up” and klasis “a breaking”. Also sp. anaclasis, refractio, “the rebounde”, “word-clashing”)

The repetition of a word or phrase whose meaning changes in the second instance.

• In the following example, antanaclasis occurs with an entire phrase whose meaning alters upon repetition:
  "If you aren't fired with enthusiasm, you will be fired with enthusiasm." —Vince Lombardi

2) Diaphora (Gk. “distinction, variance”)

Repetition of a common name so as to perform two logical functions: to designate an individual and to signify the qualities connoted by that individual's name or title.

• Example:
  "Boys will be boys."

Out of these two possibilities, antanaclasis is definitively a better choice as the second figure, diaphora, refers to ploce of common names.

The antanaclasis fits because in the expression

There are dinner jackets and dinner jackets.

the phrase takes different meaning, in one case it means an ordinary dinner jacket and in another a dinner jacket that would fit at "that table".
