The kiosk is not worth even considering if you're in the area, there are many options close by that do significantly better.
The prices you pay for the quantity you get is absurd. I ordered the KI calamari and small chips. For $18 you would expect something decent. I got a few strands of deep fried squid tentacles and the chips weren't good. I think they were store bought garbage.
When I asked the girl who served me the difference between the 2 types of calamari, she claimed not to know. I also enquired to the sizes of the different fish on offer. Didn't know that either. I gave up asking anything after that.

Plenty of people in the restaurant though. So it must be infinitely better in there.

My thoughts are it's just day care for kids of whomever is running the restaurant. They're just giving them something to do.
