Hmm. This question turned up to be a quite interesting. =DD I chose to choose people from at least a bit on the same field, it would be different answer if I told who I would like to meet and have a conversation separatedly...

George R. R. Martin, JK Rowling (heh) and Terry Pratchett.

I woukd talk about writing, their stand on fanfic and writing, tips on writing, life stories, about english language and finnish language, etc...

We would eat mashed potatoes, sautéed reindeer and lingonberry. Finnish food!
