UK, Ireland / Polish foods in Newcastle-upon-Tyne ? [15]

hi, I am also a student dietitian! I am working in belfast, northern ireland, where we too see some polish patients and i have been asked to research the polish diet so that we have sufficient information availabel to treat polish patients correctly. I can see lots of information on the net about recipes for homecooked polish food. But if there are any polish people living in belfast could you tell me where u go to buy polish food or ingredients. Is it difficult to find the foods you want? or could u direct me to useful websites? Also i have been trying to contact the polish welfare association based in belfast but cant get in touch, would this be somewhere that you would go for information?
