Up until a few years ago, a gluten-free life could be a real chore that turned dining out into a potential game of Russian roulette. In recent years the restaurant industry has become far more aware of and informed about various food allergies and is a lot more accommodating to the many diners who have special-diet needs.
In terms of what foods need to be avoided in a gluten-free diet, the list is long and includes many staples, including cereals and granola, pastas, dumplings, noodles, couscous, bread, pastries, tortillas, baked goods, breading and coating mixes, many sauces (where flour is added as a thickening agent), brewer's yeast, and beer. And for those with an acute allergy, it only takes the lightest undetected dusting of flour on that grilled fish you ordered to ruin an entire vacation, or worse.
Luckily, Las Vegas' rise as a dining destination has gone hand in hand with a general raising of awareness and a new breed of savvy chefs in the kitchen, so today many Sin City eateries, across a spectrum of ethnicities and price points, either serve guaranteed gluten-free dishes for every course or offer an entirely stand-alone gluten-free menu.
If there's a restaurant you like, check its website or better still give them a call and it's very possible that they'll be willing and able to accommodate you.
