Hamburger Union, Garrick Street, central London

You queue to order and pay before taking a seat at one of the brown tables, decorated with bright yellow bottles of mustard and red plastic tomatoes, laid out in this spartan, but modernistic cafe. The chorizo burger with rocket and peppers (£5.25) is full of colour and flavour, but the chunky chips (£2.25) are a little too salty and crispy for everyone's taste. A pint-sized bottle of Hooky beer (£3.25), a chilled cross between a larger and ale, is a refreshing way to wash down the food. This is McDonald's for grown-ups or anyone with taste-buds. 7/10
