Best doughnut in Melbourne?

Is this the best doughnut in Melbourne? It could well be; it's definitely the best one I've tasted in a long while. Except for the amazing Polish plum jam donuts from Europa bakery in Acland Street.
It's a bomboloni, or bombolini, or bomboleo or something bomby from Dench's at 109 Scotchmer Street, North Fitzroy, almost opposite the excellent Piedimonte's supermarket on St George's Rd, where I can find all kinds of weird and exciting imported European foods, as well as any type of exotic dairy I want (sheep's yoghurt, quark..). That pocket of North Fitzroy is a foodie haven; if you haven't had brunch at The Greengrocer, and finished it off by picking up a block of Green & Black's chocolate, then I say, go treat yourself!
The donut is a typical deep fried, yeasted donut filled with custard, but superior in every way. It seems I'm not the only blogging fan, either (and his photo is much better 'cos you can see all the custard). The custard is light and eggy, with a hint of lemon - real Italian custard. And the donut is not heavy or leaden, even though it does pack a punch calorie-wise; your paper bag turns transparent from the oil pretty quickly. Eat up! They're tossed in sugar, so each bite is a mouthful of crunchy sugar, light donut and creamy, lemony custard. Ok, so not an everyday treat, but as occasional indulgences go, one of my favourites.
Dench is known for its sourdough breads, which are mainly supplied to restaurants around Melbourne, but they do have a shopfront selling products, and a few tables for breakfasts & lunches packed in pretty tightly. But for me it's all about the bombolonis.
