My friends and I visited Oxford's Cooking after we heard that it had been undergoing a bit of a re-furb and we couldn't resist the temptation of another Vaults/Alpha Bar standard meal. All I can say is we weren't disappointed.
Firstly it does exactly what it says on the tin. It's a place for people in Oxford who cook and are looking for high quality, healthy ingredients, but it's also a place where you can enjoy a delicious homecooked meal or cake made using fresh local ingredients.
The coffee is all fairtrade and they cater for just about every taste in tea imaginable, not to mention providing for people like me who are lactose or gluten intolerant. It's great to find somewhere that believes in its own products so much that they use them in their cooking (or so I was reliably informed by a member of staff).
There are alot of negative comments below but they are all very old and this is definitely one of those places that is worth a second look.
