It's moved. Go here
I'm glad to be able to point visitors to this shop just round the corner from where I live in Oxford. For those of you trying to find it, it's on the corner of Bullingdon Rd and St Mary's Rd, not actually on Cowley Rd.
This is what I wrote in Aug 2007
On our route to look at a house to rent (houses in Oxford being too expensive to buy unless you have lived there all your life) we spotted this shop selling Polish products. Unlike the Baltic shop on Cowley Road (our multicultural highway) which sells mostly things in tins, this shop offers fresh food from Poland. I suppose now that all budget airlines fly to Poland everyday from several places in the UK, it could actually be fresh. But not the frozen food, surely.
However stuck away in a side street is not a good location. This shop has already been a Brazilian shop then a Portuguese shop. But probably there are more Poles in Oxford.
