Hi there, @isdarmady. A culinary festival! 😃 That sounds like a buffet. You get to walk around, sniff the aroma of different dishes and decide what you want.
I've never tasted any Japanese snacks or yakitori before but it looks mouthwatering in these pictures. I would definitely have added extra chilli sauce. 😃😊😊
