The success of American-style restaurants chains in Korea has led further expansion plans..

Outback Steakhouse, the largest family restaurant chain in Korea, plans to open 20 new stores next year, increasing the number of restaurants it operates to 90.

This year, Outback focused on opening stores in Seoul and large provincial cities, including Busan. Next year, it plans to advance into smaller local cities, including Wonju of Gangwon Province.

TGIF opened eight new shops in bigger cities, including Busan, Daegu and Changwon, this year and renovated its shop in Nonhyeon-dong, Seoul, which opened in 1994.

TGIF estimates its sales to increase to $105 million this year from $96 million last year.

Bennigan's has added six new shops to its chain this year. It plans to set up 14 more next year in cities like Ulsan, Cheonan, making the total number of shops 40.

Sun@Food, which operates three restaurant chains - Tony Roma's, Mad for Garlic and Spaghettia - opened six new shops this year, including four for Spaghettia and one for Mad for Garlic. Next year, the company intends to establish nine new stores.
