HIYA was parked outside of Birdsong, the day after the Eat a Peach release. There wasn't really a long line but these guys seemed pretty overwhelmed and backed up on making orders. My ten minute wait turned in to 25. Had I know this I probably would have taken a pass, as we had other food stops on the agenda.
The Chicken Katsu sandwich was hot, fresh, juicy but a bit bland and definitely overpriced at $8.
The Spicy Katsu rice bowl was decent - the spicy sauce had nice flavor, but as noted in other reviews didn't have much depth and definitely was not spicy. It was definitely filling, but again hard to justify $9.
Sorry guys! Wish I could rate you higher but between the wait, prices and blandness.... You guys definitely have the potential to up your game though!!
