First, the gelato is excellent. The lime and basil sorbet was simply amazing - I would have sworn it was full-cream gelato, and the flavour sublime. Likewise the chocolate sorbet (yes, honestly!)...
Second, the rose concept is fabulous - choose your size and they'll give you as many flavours as they can, all gorgeously presented so you can taste each flavour distinctively, prepared and served with care and charm by the very good staff - they were also very understanding and careful serving my nut-allergic daughter with completely separate tools.
Third, it is more expensive than other places, but IMHO it's better and worth it for the flavours and presentation.
Last, and my only fault, paying up front (before you might have had chance to see all the flavours) then waiting to be served in what is effectively a second queue doesn't work very well for new first-time customers. It did take a long time to get served and wasn't exactly clear how it worked. But I definitely recommend you try this place at least once...
