So I ordered two of the yellowtail sashimi tostada which came with avocado shiso instead. This was light and fresh tasting but mostly tasted of avocado.
The 'prawn toast masquerading as okonomiyaki' however was really quite tiny and disappointing - disappointing because it was a really different way to serve this that I relished eating and I wished there were more of it. I could have handled three times as much, especially once I gave Stephen a bite or two. They were a touch heavy handed on the bonito flakes for my liking but otherwise the Japanese mayo and seaweed flakes made this an improved version of prawn toast.
So, the food didn't rock my world probably because what I wanted was a proper dinner rather than a few snacks, and I couldn't afford to do that here. I would happily revisit for a light bite or two before heading out drinking however, just to line my stomach.
