How to say thank you...

I went to dinner with some one that I work indirectly with last night. He is the area manager for a company we work for. He asked me to dinner to say thank you for all I do for the company I work for, which works for his company.

We had a great dinner and drinks after. We talked about work a little, my husband, his wife, kids, told funny stories, and more.

We also talked about getting together next time he comes to town. He isn't here often and only knows the people from my company here.

I want to send a thank you card but I don't know how to word it. I was thinking ...

Thank you for dinner last night. I had a great time. Hope to see you next time.

What do you think? Is that enough? How would you say it?
