A Japanese takeaway spot on Adelaide Street. The food is pretty tasty with good prices. The vegan options are marked clearly with a VG on the menu. You can expect to find options like veg tempura curry rice and teriyaki tofu donburi. They also have some vegan sushi in the fridge section like inari and tempura nigiri. They also run promotion on selected days of the week, for example, the curry rice is $9.9 on Wednesdays at the time of writing this.
It gets quite busy during lunch time as it's located in the Brisbane City. They have limited seats inside, so I'd recommend getting the takeaway and eat at one of the food courts or parks nearby.
