've been press ganged into doing the shopping for Christmas in London and am now looking for sources of good Polish food in/around London as I don't fancy bringing everything over on easyjet!
I live in Guildford, which is not so very far from London. It all depends of course, on what you consider as 'good food' and choice. Sometimes we go by car to Ravenscourt and park for free on the street. You can do that on a Sunday. There is an excellent little delicatessen very near to the main POSK building right outside Ravenscourt Underground Railway Station. If you go on further to the end of the District Line and look around Ealing Broadway, then I am sure you will find quite a few little shops where you can find food. Even Tescos now stock some polish food and soft drinks and it would be a lot cheaper than little shops which have much higher overheads.
