In fact, we returned to Scoop later in the weekend with friends and I ordered the same flavours. Scoop gelato (twice) + a Bank Holiday weekend... perfect.
Scoop has parlours in South Kensington, Covent Garden and Soho. You can also order their gelato online and have it delivered to home or workplace within Central London. Tempting... (List of flavours here.)
(My other favourite London gelateria. Probably need a real-time taste test between the two now.)
