Though I could only spot the vegetarian listings on their menu, an article / review I recently read stated that they do offer vegan (dairy-free) options. I am assuming they are fairly good at catering to cheese-free, but not sure if actually offer an alternative "cheese." Call to verify.
See their website for hours, directions, and a peak at the menu: http://lafiamma.com
