Maritozzi bun at Caffe Nero, Frith Street

This bun is definitely worth trying but because it's a mass chain, expect the bun to be a little firmer however not the stale type.
Obviously they have been chilled in the cabinet for quite a while until they are sold or they could be previously frozen.
The fluffy fresh cream is fab though, not too sweet with a faint lemon taste. 

The pistachio Maritozzi bun at gelatorino was also good, bun was fluffier and probably made from a smaller batch.
