Anal Hobit's Tip on how to get Free Food in Vegas.
1. Find The Grand Lux Cafe.. Its in the Venetian. If you are with a group, just order water. Its free. If other people are at the table, FREE BREAD comes to the table. It is UNLIMITED.. Cake some butter on the bread, and it is ABSOLUTELY DELICIOUS!! You could eat 2 loafs of this tasty treat and be full as if you had a very fufilling meal!!
What if you are by yourself you say? Well, get a seat. Order a coke. Why a coke? Becasue it has 180 calories per serving. And whats better its BOTTOMLESS!!! Free refills. Keep drinking em down. Its only $2.00 and you can easily drink 12.00 worth. Also this buys you time. Tell the waiter you are looking at the Menu, and need some time. And to bring you out some BREAD while you are waiting. Drink your coke and your free bread to your hearts content. When the waiter comes back, tell em "actually I should wait for my firends before I order, May I wait here" He will say yes. Then tell him can I get another coke and more bread please.. He will comply. Stay for 1 hour. Get full, and come back later that night for the night shift.
Youd be suprised how fufilling this bread with butter and Coke can be!
