So this bear walks into a bar, right, and asks for a submarine.  And the barman says:

"Certainly, Barnaby.  Vanilla or mastic?"

Barnaby had heard of the mysterious "submarine", or υποβρύχιο ("eepovrihio"), way back in Romania.  It's a centuries-old recipe, steeped in history and social ritual (apparently) - but basically a chilled version of candy floss.  Take a spoonful of fondant, dip it in a glass of iced water, and then put it in your mouth.  And repeat.

But he hadn't actually seen one, or got a chance to try it, until he got to Greece.  Once he'd arrived in Thessaloniki, he was excited to find that the ouzerís (just like a Hungarian wine bar is a borozó, a Greek ouzo bar is an ouzerí) still serve them!  So he could sit at a table on the pavement with the old men, watching the world pass by while sucking sweet sticky stuff off a spoon.  Bear heaven.
