I went there with friends when the menu was halfprice. We waited outside for 2 hours to get a table, since it was a decent deal.
The service was tremendously slow. Food took an eternity to arrive. We were able to tolerate that, since the restaurant was jam packed with customers lured in by the deal. The intolerable part was that half of the food that we ordered never came to our table. For example, we ordered rice and miso soup more than 3 times, they were never brought to our table during our 3 hour stay. We also ordered drinks several times and even personally asked the waiter for the drinks, and still managed to bring the wrong drinks. The vegetables we ordered were also lost in the abyss.
As for the food, the meats were not fresh, most likely they were frozen. The squid tentacles were super salty. They have less items on the menu than the korean bbq restaurant right across the street (some items like pork belly cost an extra $15 to $20).
Overall a terrible experience. Everything took forever to be brought to our table, even the bill! The manager even got angry at us when we did not leave a 15% tip and started to throw our bills and credit cards on the table. Must avoid at all cost.
