Hanging out in Vegas is only expensive if you do it wrong- classic symptoms of "doing it wrong" include:
1. Booking a hotel on the Strip
2. Paying for well drinks in a casino
3. Only eating at sit-down restaurants
4. Paying for parking. I've made seeking out free parking a game, and it's wonderful how much money you save/ few more miles of exercise you get per week!
The Market helps out with Numbah 3, and it does it well. The price for the per-pound salad and prepared food bar was 7.99 when I visited, fresh fruit was perfectly ripe, and the customer service was wonderful. They could improve their produce selection- no limes or lemons for hacking into serviceable wedges with whatever blunt instrument one finds in the hotel room. I liked the mini pecan tart, but their cannoli filling was not so great.
Will definitely come back next time I'm in the neighborhood!
