San Gennaro Grill is probably one of the last places you'd expect to go for a burger on the Strip, much less late at night.  I just stumbled upon this place because I had a late night craving for burger, was in the Venetian at the time, and needed something to absorb the big pomegranite martini I had earlier.  It's in the Venetian food court and is open really late.  I was a little turned off that it cost $11.50 for a mushroom swiss burger, but you have to expect that with anything on the Strip.  The burger was surprisingly good though and it satisfied my craving for the night.  Thinking that it was a fluke for that night, I came back again the next night and ordered the same thing.  It was still good, just as good as some of the upscale burger joints on the strip.  Would I go back again?  Maybe, only if I'm at the Venetian and don't feel like going to Grand Lux Cafe late at night.
