I have heard about this place in urbanspoon.com.
Here their atmosphere is much better than Tomodachi and gogo sushi. The staff there are much nicer and they managed to fill my cup of tea ($2.50) up quite a few times. Unlike Tomodachi, the place is actually run by Japanese and you can easily see the chefs at work.
They have limited meals, but they sure do have a lot of hot and cold snacks on the train which you can choose. Prices range from $3.60 (pink) to $6-$7 (red). There is a daily special there and today’s special was a salmon salad. But I did not have a lot of money.
You just grab whatever you want and in the end the waitress works out how much you had by counting your plates. Each plate is colour coded.
I had a salmon sushi, seaweed salad, some sort of cold dumplings, gyoza, vegetable sushi and red bean mochii.
The salmon sushi was not fresh. I think it had been on the train for quite a while now.
The cold prawn dumplings were really soggy and I found them really hard to eat.
But the seaweed salad, veggie sushi, gyoza and mochii were a joy to eat. The gyoza were nice and hot not like the ones at Chillipadi. These ones were fried.
The mochii was nice and soft and it had a nice red bean filling to it. Yummy!
I think I might have found a better sushi train restaurant in the city and it is here in Sakura Kaiten. This is wayyy more filling than Tomodachi and Gogo sushi. As this place is really expensive it might be better to go there on special occasions
