My coworkers and I frequent Osaka for lunch. We typically call ahead to order. By the time we get to the location, our orders are ready. The hibachi menu is pretty cheap for lunch and the portion sizes are HUGE! I normally make 2 meals out of the $6 dish. Great deal, right?! I always get the Teriyaki Chicken with Mixed Vegetables. It comes with either fried or steamed rice. In case you were wondering, Teriyaki sauce is a little bit sweeter than Hibachi sauce. It depends on your preference, but I like the teriyaki sauce more.
Last time I went, the host informed me that they have a sushi special on Wednesdays (Dine-In only). I can't remember if he said Buy One Get One Free or Buy One Get One 50% Off. Either way, I'm tempted to come back to try the sushi (since the Hibachi dishes are pretty good).
