Big slices, but not necessarily all that filling. Fun options. Crowded. Sizzle Pie has a lot going for it, but I do wish the huge (think almost quarter pie) slices were a bit more substantive. Slices are aorund $3.75-$4 (whole pies are way the hell more, and I don't really understand the price differential.)
Nevertheless, vegan pizza by the slice is rare enough that I do regularly go here, and to the Portland location.
Cons: not super substantial
