Posh Fish partly lives up to its name, or at least its prices do. It costs a lot for what it is, but probably isn't out of line with standard Oxford prices. There's the usual range of chip shop goodies including options like chicken nuggets. There's also a good variety of more unusual options like jacket potatoes, and some good deals with free chips. You can buy sauces and drinks and there are a couple of tables for eating in. The interior isn't really traditional fish'n'chip shop, but is more modern. It's clean and the service is prompt, if not the friendliest. The chips aren't the greatest in the world and should definitely be eaten before the go cold, but the chip portions are generous and should fill any holes caused by hunger.
