Tucked down a side street behind Oxford's not so pleasant Westgate Centre, Modern Art Oxford's cafe is a duplicity - a semi-outside space with bright hanging baskets and huge front door in the summer and a windowless, grey indoor space in the winter. However, as much as I like the former, with only an hour to spare and people to impress, the latter serves its purpose well, especially as you get sight of some sculpture as you wander through.
In reality, food trumps all at lunch. Soup, rolls, and sandwiches are the only thing on offer, but done well and with the option of multiple cakes, cookies, and some damn fine coffee, make for a great hour spent.
Oh, and they do beer...!
