Thanks for the update @halfpasteleven. I thought you were going to say that he got you a package of scotch eggs from a petrol station or something. 
Champagne, what came back on the survey? Bear in mind that shortly after you move in the boiler will fail and appliances will stop working. It's to be expected when you own a house. We had to replace the roof (including the plywood roof deck) a few years ago. That was really expensive.
Hilda, sorry to hear about your DH's dental problems. As you may recall, I am something of an expert. Here general dentists won't touch a root canal, you always get sent to a specialist. I've had several and now am of the mind that they're not for me. The procedure weakens the tooth structure and a few years later I wind up fracturing it. They it has to come out and I have to get an implant. Now I skip the root canal and go straight to extraction and the implant.
Shoes, are chocolate chip cookies popular in France? I would have thought them to be a bit too ordinary. The French have all of those lovely pastries.
I asked DH if he has any souvenirs of his time in London. He does - a white ceramic mug with "Knightsbridge SW7" on it (that's where he lived) and a plastic cotton ear buds container from Harrods that we keep refilling with American-made ear buds and keep in the ensuite. So I do have a bit of the UK chez Conduct.
