Spianata, Spitalfields Market, EC1 (near Liverpool Street Station)

Expensive but good.
Illy coffee – which is my favourite mainstream blend.
Coffee ***
Cost: £1.45
Location: ****
Comfort: *** (quite a few seats outside in the market, and on the street. Inside: not much)
Others: Nice, but expensive, spianata (thin foccacia-style flatbread) sandwiches. Salads are better value.
