Good question @moonboy403.
I almost elaborated on this. 
There’s not many things I love to eat more than grilled meat. I love Yakitori! And there’s not many things I’m pickier about than chicken. I didn’t love my beloved Aburiya Raku’s wings either. 
“Crispy“ might not be the right word. It’s about evenly cooked with fat rendered and the chewy, rubbery skin attaching the drum & wing cooked-off, some golden finish and char… for me anyway, lol. But most places only get the splotchy char part down. I haven’t had yakitori everywhere but the one place I loved the wings was this little, untrendy, Japanese spot on the corner of Wilshire & San Vicente (long closed, now Continental Kitchen). It’s my benchmark.
Aren’t you glad you asked?
