There is a lot of mixed review on Stonegrill. It's an innovative idea of DIY teppanyaki on a volcanic rock. It's novel and fun for the first meal, but that's it.
Ordered:
Mussels in white wine - Portions was good and it was tasty. You can taste the white wine intertwined with the mussels with each bite.
26-day aged AAA beef tenderloin - Food quality is top notch. But portion control was terrible. Several guests at my table ordered the same 8oz tenderloin, but some were so thinly cut that by the time the meat arrived at the table, it was almost 70% cooked. So much for cooking it yourself.
Cherry Cheesecake - Bleh. It was less than memorable. It is something you'd find in a supermarket.
Note: If you come in a big group, be prepared to be squished in your table. And the lack of ventilation in the restaurant made it almost unbearably uncomfortable.
