i was at difaras today, and having read some comments about the mushroom slice on this board, i decided to try one.
great god was it fantastic. i generally prefer the square at difaras, and i also usually prefer plain slices, but i think this was the single best slice of pizza i've ever had.
at $5.00 its a pricey slice, but it was worth it. it was loaded with large chunks of porcini mushrooms that were bottled in olive oil, and i think some other seasonings.
thankfully i can still taste it now.
