I finally got around to trying Goro+Gun. I'm going to make it relatively short, since so many reviews have been done previous to mine.
My bf and I ordered the shrimp gyoza, shio ramen and a roll.
The roll had fresh salmon, crunchy tempura and a mild hint of wasabi. Only comment on the roll was that the rice was a bit wet, making it hard to pick up with chipsticks.
The gyoza was alright, crispy bottom and a salty dipping sauce but nothing outstanding about them.
The ramen, which they are known for, is a smaller portion than other restaurants would typically serve. The hi-light of the bowl was the pork. It was by far a better quality meat than any I've seen in calgary. It was soft, fatty and rich. None of that dried, tough business with an unnatural pink circle on it.
All in all I would rate my experience as good. I don't think Goro has anything that particularly draws me back by offering anything different from other sushi/ramen places, but is worth a try if you are in the area.
