Hmm....I don't think you can go wrong with either one, honestly. If I HAD to choose, I would choose Liberty Tree b/c that's my favorite...BUT, the Crystal Palace is also really delicious.
We've had dinner at LTT twice and really enjoyed it. We've only had breakfast at CP (twice) and thise past year we were not very impressed with it. So, my vote would have to be for LTT.
