Ru sans turned out to be a chain that exists in a few cities around the country. It's not great but it's not bad either.
There are a number of creative sushi rolls that exist on the menu and have a decent selection of vegan/vegetarian options as well.
We have been here a few times which just shows that the food is good but don't expect it to blow your socks off. If you're looking for a place that serves tasty sushi, has a fun environment this is a good place to check out. But service at times has been slow.
