Xmas alone? (Lisbon)

Hi,
I've very recently moved to Lisbon and have no friends here yet.
A few months ago my mum died after a few months of terminal illness. We used to spend every Christmas eve together. I am a bit afraid of this year and really would prefer not to spend Christmas eve all by myself.

So basically I am looking for other folk living in Lisbon who are not having any family plans for Christmas eve, either, and would like to go and have dinner, a few drinks and conversation on the evening of the 24th.

Cheers,
Max
