Seoul is full of trendy and western/European style restaurants. You can have pasta , pizza , curry , naan etc ;) or French style bread. I would like to introduce couple of them : Jenny's Cafe in between Hapjeong station and sangsu station line 6. It is Italian style pasta and pizza restaurants and some of dishes use wine as ingredients Mad for Garlic. It has franchises all over Korea. Beautifully decorated from inside. I will recommend to try their snow garlic pizza :) Gangnam station exit 12 branch is not crowded on Sundays ! Try your luck there
