Grand Lux is for you if:
--You're staying in the Venetian or Palazzo
--You want to spend less than $15.00 per person for a very nice brunch/lunch
--You want kind and helpful service
--You want to be seated immediately
--You want lots of options and choices
Thus my four star review, which surprised me, since it's owned by the folks who own the Cheesecake Factory (which I consider the bastion of decent mediocrity).
Everything we had was uniformly good, and one item--the Duck Triangles (crispy wrappers filled with minced duck, onions, garlic, ginger, soy and sesame)--was absolutely stunning.
We left feeling full and pleased.
