On the outside, Ha Ha’s Grill House looks like the other industrial buildings on this stretch of Garland. Then you open the door and are hit full in the face by a lovely atmosphere of green and yellow walls, dotted with various (mostly classical) record albums and contemporary décor. Chef/owner John Ha plays with recipes inherited from his mother, Soon Ha, and only works with organic and natural ingredients. He describes Ha Ha’s fare as “Euro-Korean fusion.” (BT, 9/10)
