Ed love your avatar, harking back to the glory days of steam and liner travel...looks great. Nice picture too of Boulogne and it does indeed bring back memories. The old walled town there is a real treat. bit of a hike up the hill but well worth it.
Thanks for the tip Andy re the restaurant, might get over to try that. I was inside the church you refer to and have a picture of the stained glass windows from it somewhere in the system...popped in after enjoying the market right outside.
Ive enjoyed all the towns listed in the press release above at top of page, Wimereux, Le Touquet, Etaples and of course Boulogne but have never been in Montreuil. Dont know what thats like.
