I enjoyed Crack Shack the 3 times I've been there. Thought the chicken was very well fried, not greasy, moist inside with a nice crunch. The shmaltz fries were excellent as were the biscuits and soft serve ice cream.
A great thing about Crack Shack is the full bar. It's nice to have a cold beer with fried chicken.
OC doesn't have a lot of great fried chicken. Te best fried chicken I've had recently in the OC was at the new McFadden arcade place in Santa Ana. Crack Shack is certainly better than Ms Bea, Roscoe's, Ms Knotts and some of the other places that come to mind. This place is going to be packed from day 1.
