Are they in France or Portugal at the end of Love Actually?

It's been awhile since I saw the film, so I might be wrong, but I'm assuming they're in France. The main reason I'm guessing this is because Jamie doesn't have Aurelia's address - all he knows is where she used to work for him, in the house in France.

As for her and most of the people he encounters speaking only Portuegse, it is possible that A) some of the people (at least in the restaurant) do speak French, but seeing as how they're at a Portugese restaurant, they would revert to their native language; and B) it's also possible that some of these people (such as Aurelia) genuinely don't speak French, but manage to get by with the help of their community. I live in Holland, and although I learned and can speak fluent Dutch, I keep hearing how many people speak only English (granted, Holland has a lot more English speakers than France does, but still).

It's Bar de la Marine in Marseille.

Jamie tracks Aurelia down in an area that is probably inside of (or near) Marseille. There are a lot of Portuguese-heritage folks in that area of France, partly due to immigration by Portuguese sailors. According to a Wikipedia entry on the demographics of France, "As at January 2006, INSEE estimates that the number of foreigners living in metropolitan France amounted to 3.5 million people. Two out of five foreigners are from Portugal, Algeria or Morocco. It is interesting to note that immigrants are concentrated in the Île-de-France, Rhone-Alpes, Provence-Alpes-Côte d'Azur (Marseille) regions, accounting for 60% of the total immigrant population.

The article estimates that there are more than a 1/2 million Portuguese immigrants in France.

I am sure that Barry got it right.

I check out the movie last night and the airport that he landed at was the Marseille Provence airport. This is located in the South East corner of France. It would not be a very convenient drive in the taxi to go all the way to Portugal from that location.

Although the restaurant where it was filmed may actually be in Portugal, there is no practical way the guy would drive from Marseilles to anywhere in Portugal. Not logical. There are many expats of Portuguese decent living in France; there are many enclaves. That is what was intended in the film. Although ... it is certainly not clear in the movie. They mostly work in construction, or in the service industries, as did Aurelia. Their numbers are substantial enough that they have their own neighborhoods and restaurants.

I know that restaurant, it's located in Porto, Portugal, I know he arrives to Marseille Airport but I was in that same restaurant some years ago, I'm trying to remember the name of it, and I'm definitely looking for it in google maps, it's located in the riviera, (next to do Ouro river)
