I don't know what it is with this place but my gf and her family love this place. For me once I've seen the show I've seen it a thousand times and it is old. Of course, the kids love the show and love the [irritating] birthday song of which they will sing every day until the next birthday that is held there.
I have tried the grill and the sushi and neither has truly impressed me. The grill is hit or miss and probably depends on the chef and how much seasoning they put on the food. The sushi was OK but a bit on the expensive side. I think I would have enjoyed it more if I had come starving instead of arriving already content. Normally I will eat 3-4 rolls and this time I couldn't even eat two - the rolls are the larger diameter rolls BTW.
The servers do keep your glasses full and are poignant on checking on you without being annoying. This is a big kudos to me as this is a fine balance of feeling forgotten and feeling annoyed.
I judge for what it is worth and this is a place for parties, not gourmet food served under candlelight. Chances are you will hear that annoying birthday song and see someone running around with an paper-mache Asian-face helmet on - that is just how it goes. It is good for this but I do dearly hope on a regular basis that the GFs family picks something different for the next birthday because going there every month is too much for me.
