Are Elves vegatarian?

In the films, the dwarves were rude and mannerless, and the elves haughty and disdainful. Hence I wouldn't be surprised if serving a subpar dinner to the dwarves, accompanied with music and all, was an act of slight with finesse, whether it be in revenge for their poor manners or as a general "eww dwarves" notion. What saddens me most is that neither of the races is supposed to be like that.

Yep! Professor Tolkien's characters are grey shaded--neither black nor white. And despite showing them flawed they are shown lovable and that they are. Movies seem to rob this from the characters.
Though in the book I found Dwarves quite ungrateful. They were cool when Gandalf was with them, but when he left they would be angry, why? When Bilbo did more than he himself had imagined to do, still for Arkenstone Thorin forgot all! Perhaps this is because of the naive understanding of the text and characters; and I'd certainly like to change my opinion about them. But so far many things done by Thorin and company, I didn't find "noble". Yet, I like them all.
For the Elves, I hadn't liked Elrond in LotR:TTT much, and couldn't like him TH too. While in the book he is a different character. Perhaps what you said is true. I'll stop now.
