Thankfully, no restaurant can actually fit in your back pocket. It would be far too messy. Even in a Honey I Shrunk Our Local Pasta Restaurant situation it would just be annoying. Little waiters trying to serve tiny portions of puttanesca before you crush them in search of that loose pound coin. But if we could have Stampa in our back pocket all over London, we wouldn’t be displeased. Because having the constant option of handmade rigatoni carbonara (complete with guanciale) for £7.50, or pici cacio e pepe for £6.50, would be very welcome. That’s what this simple little 20-ish seater corner café and restaurant offers. It’s only open throughout the working week, but the hours run from 7am until 10pm. That, combined with the very good pasta, would make it a useful restaurant in any of London’s neighbourhoods, but especially in Mayfair.
