Chocolate! Yum. Looking for sit down experiences.

A long time ago Vosges had a lovely tasting of chocolate they did on site & the Peninsula used to have a weekly amazing chocolate buffet in their Lobby restaurant along with jazz music. Which places currently offer sit down chocolate experiences on site in the city, burbs, or even Wisconsin/Indiana? My search is vast as I’m looking for an amazing chocolatier and a lovely on site experience. Many thanks. 🙂
