Among the items he's tried are tuna pies in Thailand, "sir sombreros" - or fried cheese shaped like sombreros - in Serbia, chicken sausage burgers in Malaysia, a crab croquette burger in Okinawa, Japan, and sweet potato fries in Singapore.
McGowan, a software developer, writes reviews of the food on his blog, McDonald's Around the World.
Here's a map of all the McDonald's restaurants he has visited:
McGowan told the Wall Street Journal that more than two million people have visited his blog."Strangers say, if you're fortunate enough to go to all these countries, why do you waste it on McDonald's?" McGowan told the Journal. "I like sharing online. People seem to enjoy it. And I don't gain weight."

McGowan most recently tried a burger in Sapporo, Japan, featuring bacon, beef, cheese and mashed potatoes. He said it was "easily the the worst promo burger" he's ever had in Japan.
