It's my mom's bday tomorrow and we are planning to go out to dinner. She lives in Diamond Bar. We are chinese so instead of the normal chinese fare, i wanted to take her somewhere different. Since it will be a friday, I dont want to drive too far and be stuck in traffic. My father likes steak and good japanese. My mom likes anything. We've done the Pomona Valley Mining Co. but that was just ok. We go to Rokuan for japanese pretty frequently so we dont want to go there. No mexican or italian (not unless they have some spectacular steaks). I am willing to go as far east as Chino, as far south as Fullerton, west as Hacienda Heights and north as Covina. Any reccomendations?
