Mos Burger, established in 1972 operates outside of Japan in Singapore, Taiwan, Hong Kong, Thailand and now Korea. Mos Burger was the first to develop the teriyaki burger and a burger using a bun made out of rice (rice burger).
Korea has two distinct markets for burgers: the inexpensive fast-food market dominated by McDonald’s and the upper-tier burgers captured by Kraze Burger; Mos Burger is going to position itself somewhere in the center of these two groups.
