It's been a while. Great Seas on Lawrence in Chicago has moved across the street. The original owners have retired and not sure if it is run by the same family anymore. The new digs are much bigger and nicer. One of the waitresses remembered me. The chicken wings were still good but definitely not like the past. I haven't been there in close to 7-10 years. It just reminded me of what it used to be. I also know they tried a 2nd location near the UIC campus that didn't work out for whatever reason. I think either the kids of the original location opened up another location at 1705 W Algonquin Rd, Mt Prospect, IL 60056 that serves a limited menu of the the wings and shrimp. They had a picture of the original location in the restaurant.
As for other types of Korean fried chicken. Believe it or not, I am not a huge fan of Korean style fried chicken. IMO, it is too slathered in sauces and I think it drowns out the chicken. Some places give you plastic gloves to eat this stuff. I do like the small cube radishes in the clear "sauce" that it usually comes with. It is a cousin of the normal kimchee that many might be familiar with. My wife has learned how to make this and we store it in our kimchee refrigerator. Great with other dishes also. Another thing I noticed is that these places charge way too much for what you are getting.
There is a place in Glenview called Fly Chicken on 952 Harlem Ave, Glenview, IL 60025 that serves the wings this way. As an appetizer, I might eat a couple but not as a meal. I do miss the original Great Seas.
