Erm, that's a bit of a tough call. Zack and Wiki on the Wii, which is out soon, is in a similar vein to Monkey Island (it even has a monkey in it...) but that's a pretty pointless suggestion.
Only one I can think of out of my collection is Paper Mario: The Thousand Year Door - which is thoroughly awesome. It's not really what I'd call an adventure game, but it's fairly reasonably slow paced and has some decent puzzles. Adventure games like Zelda aren't really anything like Monkey Island.
Not quite Monkey Island vein, but 'Beyond Good & Evil' is pretty funCombat is easy, and gameplay seems fairfly unique with the photography bits (and enjoyable)
