This place is great. The space is a little crowded when it gets busy, but the atmosphere and service is really nice.
PSA: The lunch time bento boxes they sell for $14.85 are an INCREDIBLE deal. You get an insane amount of delicious food and they have lots of combination options including sushi, tempura, beef and chicken dishes. They also are served with rice, salad and miso soup. I very reasonably could have eaten half and then saved the rest for dinner, but it was so good I stuffed my face.
The sushi prices are pretty standard for Calgary, as with the ramen. I have only tried the miso ramen, and it was very good with the option of lean or fatty pork.
This is definitely one of the best options for Japanese food in the city.
