What a fun experience! I've been here several times and I love cooking my own food on the grill in the table. I've tried the bento boxes as well and those are pretty good. I have only tried spicy items and none have been spicy. On my next visit, I may see if they can kick it up a notch.
There is a minimum of two dinners when you want to cook at the grill even though one could feed two people. This is a great spot for a small group or double date. Two dinners is plenty for 4 people and it's a lot of fun cooking your own meat and veg and then adding the toppings of your choice.
