In terms of sustinance, Pisa works just fine. The expectation that a hot and fresh slice is available any time of day is a pipe dream. I asked for a slice of cheese at 4pm, and I got what I deserved...a slice that's been chillin under a heat lamp with no discernable taste and cardboard texture. Though I am grateful for the nutrients that it provided so that I could tackle Sin City nightlife...hence 2 stars!
