Ray Williams has eaten at McDonald's in 34 countries.
The travel-show host and producer, who once made headlines for crowdsourcing an effort to get legendary chef Anthony Bourdain on the air, says the fast-food giant is a comforting taste of home on the road.
McDonald's restaurants in Australia and France have a reputation for being better than those in America.
Of all the McDonald's he's tried, Williams says Thailand does it best.
Here are a few reasons he thinks Thailand has the best McDonald's.
1. Most sandwiches are available in double size.
"That's four patties in some cases," Williams said. "A double Big Mac is never a bad idea."
2. Samurai pork burger
One of the best-known menu items in Thailand is a burger with a pork patty, teriyaki sauce, shredded lettuce, and mayonnaise.
Williams says this "burger" — which is like a cross between a McRib and a Big Mac — lives up to the hype.
Other exotic menu items include spicy chicken, served with eggs and rice.
