we arrived early hence we do not need to wait too long to get to our seats. However the table are very close up , i can hear what the other table customers are talking about . So thumbs down in terms of privacy. 

we waited quite awhile 15-20 minutes before our food arrived. we ordered fried kaki which is fried oysters , it is not too bad. The sauce that goes with it is nice. We also ordered cold soba with tempura. the ebi was tasteless and the soba was alright. the tamago katsu was standard not too bad. the chocolate parfait has too much cereals and too little ice cream to go with it. the mango yakult drink was nice though. 

the waitresses are quick when u need their aid . getting the bill was fast too. 

but all in all i think watami branches in taiwan are much nicer in terms of space , ambience , food and service. 

sequence of events
waiter spilled 7 cups of water on my friend's jeans and shirt. proceed to continue waiter-ing others after clearing cups and left the table and floor dripping in a mess.
scolded them. the food took 1 hour to come. it was just sashimi rice. a bowl of  hot pot egg rice thing took 1 hour and 20 minutes to come. we timed it. we reminded them time again but they still took so long. 
food quantity was pathetic. the scallops (8 in the menu) was as big as 3 of the ones in itacho. the salmon sashimi was stale. 
i told the staff to give my friend with water spilled on her, a complimentary meal. she said sure. when the bill came, her food was not discounted.
i asked for the manager, and staff said "manager is on leave, sorry." along with an apologetic note.
all in all, it was terrible. for the same price, eat ginza kuroson, itacho, sakuraya fish market. watami (STAR VISTA) is hilariously one of the worst places ive been to. i set up an account just for this.
 

I did not wish to have came and write a review here but they left me no choice by not having an email address to express my feeling.
29 October 2012,
Me and my gf have visited them at 7.15pm and was seated right away. We have ordered Salmon sashimi, Tokyo gyudon and Mentai potato pizza. Service from the waitress were good, unfortunately there is a waiter look around 40's has spoiled our night.Sashimi didn't took long to came to table, it wasn't taste fresh but acceptable.
85% of the pizza was soft, there's a little crispy on the side of the pizza. The rest, was soft and soggy. Me and my gf did not mind about it. But I did not expect the pizza would be served that way.
Tokyo gyudon, was a disaster. The beef was too dry to put in my mouth. Egg yolk was hard. And there's no sign of sauce on the beef. I asked the male 40's server if the Tokyo Gyudon should be served that way, he answered 'Ya that is the way' and when I explained that the egg yolk was too hard and the beef is too dry. He said 'Oh the sauce has gone bottom of the bowl and if you want I can chance the egg for you' Well. I did scoup till the bottom and I see no sauce. I asked him if I can change to something else, he denied me and insist only can change the egg for me. I believe even if I would accept changes of egg, the rice would have get cold. And then, I asked the female server if I could change to another dish, she straight away agreed if I want anything else. Then I took a little of time to look through the menu. The male 40's server came to me and said ' yes sir, you can change to anything now ' . With that attitude, he have spoiled my night.
I would appreciate if Watami could do better on food standard with the price they're charging.
I am definitely would not be going back Watami after a disappointing visit.
