From my experience, they love outings in the country, lots of beer and wine. Learn to toast they way they do - it's quite elaborate. They do know "Asian" food, but may not like spicy food or seafood. It's not typical for them to split a bill, unless there is a really large group. Do they hug? Yes. Is it appropriate for business clients? No.

Czechs love hugs. In fact, Czech guys are extremely skilled at communicating with women. Of all Europeans they are the most skilled. Don't worry too much about him. He will entertain you. Have a great time.
