The best restaurants serving Other european-cuisines food in Cathedrals Southwark London

I bought a Time Out meal offer and was told to book the table and send the voucher in, which I did. I was then emailed 10 minutes later, to say the restaurant was booked for a private party that night. I couldn't make another date, so I asked for a refund on the £50 voucher I had bought. A month later and 11 emails later and I still don't have a refund, but lots of excuses why they haven't repaid me and hollow promises. What a shame!
