As someone who has been to some of the best Korean restaurants on this side of the world, Ha Ahn can dish out some decent Korean cuisines. They usually serve 6 banchan dishes that change every time I've been there. The tofu soup isn't as fresh as I'm use to but the soup is still full bodied. My favorite is their galbi: not the traditional way with bone-in but served generously with a dark sweet teriyaki marinade.
They also have good lunch specials but only served M-F. Great Korean restaurant if you don't want to drive all the way to Parma.
Tip: This gem is hard to find. It's in a tiny plaza with Superior Pho with a parking lot in the back, accessible via E 31st at Superior Ave.
