Really California Sushi and Rolls at Snowfox (Gyodae exit 8)
Finally a decent rice roll place in Korea. It's a fast casual concept but stylish and good. It has a California flair with lots of avocado and rolls that are well balanced and not just sopped in sauce. Nice cuts as well. I got a great California roll that was big enough for lunch for 7,000 won. I will be back Snow Fox by Gyodae (Seoul National University of Education Line 2 and 3). It's right outside exit 8.
