Stripburger, across the street from the wynn is pretty good. The burgers are tasty but what keeps me coming back are those sweet potato fries.
Also, my favorite thing to do in Vegas is to eat on the patio of the gran lux cafe in the venetian between the hours of 2 and 4 in the morning. The foods good but the best part is watching all of the sloppy drunk people come out of Tao and go to their rooms. Youll see everything from chick fights to passed out guys wheelchiared to their rooms by security. Best dinner n show IMHO.
