I was in the mood to try Tepanyaki and Ah-So is much closer to me than Benihana's.  But I was not happy with the food.  It was not as tasty.  The fried rice was pretty bland.  The soup they bring you and the salad were pretty tasty and the shrimp we got was worth it.  I don't think I will go back though b/c it just wasn't the same as Benihana.  For as pricey as it was, it just wasn't what I hoped for tastewise.  Meh.
