There's a huge Yemeni Jew population in Israel and their food is among the most popular. It's a lot of grilled meat (lamb and chicken, mostly) with breads and spicy condiments. Whenever I'm in Jerusalem, I head for this place first (the website is in hebrew but if you scroll down you'll see what the food looks like). The combination of a spicy zhug with malawach (sorta like pita) and lamb stew is pretty hard to beat.
Singapore has the best variety available anywhere, Chinese, Indian, Malaysian, Mauritius had the best seafood curry on the planet hands down. Thailand, Greece, Turkey, and Spain for honorable mention.
I'd give France and Italy a big meh,

Armenia. Ate a lot of Aremenian food in the Fresno CA area.
Old Mexico, as in the center of the country and also far south along the coast. Baja was nice, especially the homecooked food at the case de Antonio, of Antonio's Whale Tours, Campo Fridera, Laguna San Ignacio. First night we were there, he let us camp on his place and invited the 7 of us to his house for a lobster dinner cooked by his wife, all for just bringing a letter to him from his brother in the town of San Ignacio. And he made hacha ceviche a couple of days later and took us out in the panga to get close to the whales. I've never been far south in Mexico though to sample the regional cuisines.
Argentina might be nice. India, Thailand, Indonesia, PI, Vietnam. Japan Mongolia Russia/Georgia/Ukraine Most anywhere around the Med, as I love food from there. Sicily is on a short list, but no longer having a desire to fly I'll likely never get to Grandpa's native village.
Maybe Greenland, so I can try whale and walrus and such.
