Foodie heading for tavern after exam in postwar capital (3,6)
I believe the answer is:
Here is my best explanation:
'foodie' is the definition.
(person who enjoys a life of luxury)
'heading for tavern after exam in postwar capital' is the wordplay.
'heading for' indicates taking the first letters.
'after' is a charade indicator (letters next to each other).
'exam' becomes 'viva' (short for 'viva voce', an oral examination).
'in' is an insertion indicator.
'postwar capital' becomes 'bonn' (capital of West Germany).
The first letter of 'tavern' is 't'.
'viva' going within 'bonn' is 'bonvivan'.
't' put after 'bonvivan' is 'bonvivant'.
(Other definitions for bon vivant that I've seen before include "One who enjoys eating and drinking", "one enjoying best courses", "Gourmet", "He's fond of good food and wine - in France", "> who likes the good life?", "One living luxuriously", "Jovial companion" and "Hedonist".)
