I absolutely cannot stand Mario Batali. He bugs about the same as Bobby Flay, but not as much as Rocco DiSpirito. The BF and I were in Las Vegas for the BF's brother's birthday and we needed a place for lunch. We decided on Enoteca San Marco before I realized it was a Mario Batali place. As we walked in, I saw an autographed pair of Batali's trademark day-glo orange Crocs ON THE FOOD COUNTER. The Crocs were obviously too small to support Batali's rotund frame, but it was gross to see shoes on the food counter. Given the amount of Asian business that Vegas gets these days, Batali should be aware that putting shoes on the food prep counter is a tremendous offense in Japan. Bobby Flay found that out on Iron Chef.
Anyway, the food is okay. It's a small plates concept and you'll spend $30 - $60 per person for lunch before you get enough to eat. This is nothing like eating in Italy, but it's passable. The gelato was good and they had interesting flavors like blood orange and grapefruit.
The faux Venetian atmosphere adds a bit, but it is quickly offset by the "free" singing that occurs hourly. You get to endure costumed shrieking for up to 20 minutes each hour. It really detracts from the dining experience and heightens the fakery of the setting.
There are better places to go, but if you're trapped in the shopping mall attached to the Venetian, this place is an okay choice.
