We've gone here a number of times for gelato and it's definitely solid. My litmus test is always the hazelnut (called nocciola in most gelateria, but weirdly not the case in this trendy joint). There's is pretty good - not the best in the city, but certainly above the bar for what's worth coming back for!
But here's the added twist: they have awesome brunch! We went there this past Sunday and were totally impressed. The mini-croissants are flown in from Belgium and then baked fresh each morning. The lattes - very good, fresh squeezed rocking OJ, and one of the best hot chocolates my kids (who have lived in Switzerland for a year) have ever had! If you're very hungry or dining with teenagers, you might find the portions a bit small. But at 40-something, small potions are not a bad thing!
