>Cafe Bonaparte

Google says they're permanently closed. Do you know if that's the case?

Delirium Cafe has two locations. Brussels, Belgium and Leesburg, VA.

I have been to both and while nothing compares to the original the one here is a lot more accessible :)

You could visit the Leesburg location and get some pretty cool stuff for your grandpa. However, if he lives anywhere in the DMV area my suggestion would be to take the time and take him there yourself. I bet he would think that's the best present. Happy holidays!
