Should you blow your bankroll:
Gold Spike - The 24-hour restaurant which closes once a year for an hour of cleaning is one of the most amazingly cheap places to get food anywhere in the world. The prices and ambience will convince you you're in the Third World. (2 for 1 coupons available for hotel guests.) Complete ham or roast beef dinners are $4.50, potato salad is $0.60, and on and on. Everything on this menu is budget priced. Full (sort of gross) breakfasts are $1.99 before 10:30 a.m. Also, if you're a guest, you get free breakfast for two every morning
Westward Ho - In the tradition of the old West, shoot up some cattle rustlers and then eat a 1/2 rack of ribs for under $5, a 3/4 lb. "Mega-dog" for $1.49, or pay $1.99 for a mammoth strawberry shortcake which will only taste good to you if you have never eaten an honest-to-goodness strawberry shortcake. The 3/4 pound hot dog is the biggest in Vegas, but you have to be a real trooper to eat it. Really, the first six or seven ounces taste fine, but then diminishing marginal returns set in and you'll hate yourself before you're done.
You can always get a cup of joe at the Ho for a nickel, or a gourmet cup for a quarter.
