i ate there once, its kind of interesting as its a fusion type place, but it is run by koreans...i remember liking the pear and pork appetizer, i think we had the kalbi jjim although we weren't a huge fan of it...its probably worth trying though, i should probably go back sometime
btw the korean food on 32nd is generally nothing to write home about (a few places are good), if u want some good korean food you'll generally have to hit flushing
It's not exactly K-Town - you don't get a lot of banchan for starters. I've been there several times - I usually go for the soon dobu, which is deeply delicious. But the food is usually of a good quality and prepared with care. Try the pear and pork delight. The japanese pumpkin soup is also tasty if available.
I think the places on 32nd might be more "authentic" but I can't think of any place that I'd rather go instead of going to Sura. Definitely recommend that you check it out.
