An assessment of Koronet's jumbo slice ($3.75) must take into account not just the sprawl — that silvery dot is my 25 cents change — but also the heft. Even at this size, a slice is sturdy enough from lip to tip that you can fold it and eat it with one hand, though you'll also appreciate a place to rest your elbow.
