Blink and you'll miss it.
There are at least 3 other locations within walking distance, one within the same complex if you want to eat in, only one small table and 2 chairs here.
This location is good for summer as they setup a few tables outside or you can sushi away during the festivals.
As for all sushi shops, they are a bit pricey, and this location seems to make mostly pre-made sushi and some items from their main menu are not always available.
