Located in the food court on the casino floor of the Venetian is the Rialto Deli. I paid it a visit because I wanted to use my 20% off ACG coupon. I ordered a french dip sandwich, onion rings, and a drink. It came to about $11.
The french dip was average portion, but tasteless. The au jus was tasteless. A small container of cole slaw was very good. The onion rings were very tasty and a large portion.
Two stars is all I can give it because of the lackluster sandwich, but you could certainly do worse.
