I love Hibatchi, but sadly Sumo did not live up to my expectations.
They really need more servers, as ours was spread very, very thin. Plus they really should have cooled the restaurant down more than they did. Everyone at our table was very overheated.
Our chef cooked ALL the proteins at the same time, and was not quick enough to avoid overdoing the shrimp and calamari.
I've never seen a Hibatchi chef start all proteins at the same time, and now I understand why. Quality goes down for all.
The prices were decent, and Hibatchi dishes included fried rice. The ingredients seemed fresh, if only they were cooked properly.
To us, Sumo was just not worth the 30 minute car ride to eat dinner there.
