My friends and I went into Grand Lux Cafe at the Venetian for a late dinner and drinks.  The food was OK, our server was reasonably pleasant, but the night manager Matt Timms, when questioned about the cost of an item on our bill, was so off the charts rude- my friends and I will never come back!  Mr. Timms even went so far as to threaten to call my girlfriend's employer to make her look bad when he learned we were locals.  I've never seen someone lose their cool like that, especially not a manager.  There are many better options for restaurants within this casino.  Beware!
