I've dined at Dimmi several times over the years, and I can't recall ever being disappointed. My favourite dish is the gnocchi in tomato sauce: melt-in-your-mouth morsels, that taste like an elderly nonna rolled them in her old-country kitchen. Others rave about the pizzas; I like them too but they are pretty comparable to other Italian restaurants in the city (Ciao, Grazie, Terroni, etc.). Dishes are generous portions and reasonably priced, considering Dimmi smack dab in the middle of ritzy-glitzy and normally expensive Yorkville. As for celebrity sightings, I've never seen any Hollywood A-listers at Dimmi, but I did see Canadian Food Network host David Rocco dining on the patio once (he's supposed to know good Italian food, so take note) and the lead actor from the "The Listener".
