I've been to several hibachi style restaurants in the area and this is by far my favourite. The food is excellent. I am a huge fan of the soup and lo mein noodles.
This is an excellent place to go with a group of friends. The chefs are entertaining and the staff has always been pleasant. If you aren't there with a group or for a birthday the atmosphere can be loud. its definitely not a place to go if you want to have a nice quiet dinner.
Lunch is also incredible. You get a slightly smaller portion than the dinner menu for about half the price.
Ichiban is definitely on my list of places to eat when I am back in Pittsburgh.
