I can't even imagine how much chicken this place goes through in a week.
Anyway, the chicken teriyaki is great. They marinate their chicken and have a tasty balanced sauce that goes on top. I think it's only like $6 for a plate which is plenty for one person.
Sometimes they're a little inconsistent with portions and cooked-ness. They cook the chicken in large amounts at a time, and when it's done they keep it on the grill so I think sometimes some of it gets overcooked.
I can't speak for the other things on the menu, but I probably wouldn't get anything except the teriyaki.
