One word bombolone. Get yourself a custard or Nutella filled Italian doughnut you'll have no regrets. There are three sizes for those that are diet conscious or on a budget; bombolini (new mini) $2 or 6 for $9, small $3 or large $4.50. The perfect proportion of filling to soft doughy goodness with a sprinkles of fine sugar on top.
Tried a sample of their flatbread Margarita pizza and it was amazing. Next on the list to try.
Don't let the small size of the shop scare you away, there is plenty of seating upstairs (one large communal table).
