Good food, great selection, large portions, and open late! I frequent the Grand Lux Cafes every time I stay at the Venetian/Palazzo because it's easily accessible and open 24 hrs! It's essentially the go-to spot when I'm hungry and can't figure out where to eat or when I'm with a group who can't agree on a place.
There is rarely a wait to be seated (especially at this location), but the wait comes with getting your meal. Service is so-so, sometimes they don't even bring bread to your table while you wait for the main course which makes me hangry. None of the dishes were memorable to me, but I always come out of this restaurant full and content.
