One hundred and fifty percent agree. Danube was one of the best meals I've ever eaten (anywhere). The food is great, the staff is attentive and the room is just so beautiful. If you check out my profile, I have a link to my blog, where I wrote a review of it a while back.
Haven't been to Chantarelle, but have been to Daniel and Danub, both with my mom who has been to all three. Of the two I've been to I would say Danube and I know she'd say it of the three.
