A different kind of after dinner pick me up

Now, before you jump to conclusions, let me explain...

On February 28th, Matthew and I went to Stout for our third anniversary. Dinner was great (we went with the tasting menu which was very impressive) and by the end of the evening we were pretty satisified and opted not to go for dessert. When the waitress came back to the table, she set down not the bill, but a tray with a mirror containing a pile of white powder, two razor blades and two straws. She leaned down rather cheekily and with her chin in her hands said "Now kids, this isn't what you did last night, this is actually a candied sugar dessert. You'll inhale the sugar slowly through your mouth, not your nose. Compliments of the chef." And with that she left the two Americans sitting there in complete and utter amazement to go to town with what turned out to be their very pop rocks like dessert.

Only in Amsterdam.
