Korean Food in Boca
You have 3 choices. Your best choice is about a 35 minute drive into Tamarac for Gabose. There is another Korean restaurant in Lake Worth (about 35 minutes also) -- name escapes me.
The closest is a Japanese restaurant in Coconut Creek (SR 7) called Sushi Yoshi. It is a Japanese restaurant but they have a sizable Korean menu. Not bad.
