You might be skeptical if a travel guide told you to eat lunch at a convenience store. In many countries, convenience store food is viewed as a quick, practical option rather than a gourmet experience. However, in Japan, the “Konbini Egg Sandwich” (Tamago Sando) is a culinary masterpiece. The late Anthony Bourdain famously described the one from Lawson as “unnatural, inexplicable, and delicious.” It has since become a must-eat ritual for chefs and foodies visiting Japan.
