I think The Firkin in Libertyville has a tin ceiling, if that's not too far north for you.
I have a non-restaurant idea for you, though. How about a party at home for you and your wife and the people who've helped you make it through the first ten years: a picnic theme, inside or out depending on the weather, several picnic-style dishes cooked in and/or wrapped in tin foil, and on the same table but separate from the food items, a present for your wife wrapped in tin foil rather than regular gift wrapping, and take-your-pick presents for each of your guests also wrapped in tin foil (for surprise effect).
Do you like this idea at all? I do! Now I have to wait seven more years to try it out myself!
