It's a cute concept but meh.
The place is clean, the service good, and the decor engaging.
But, the ramen isn't worth returning for. The soup base is bland, the noodles aren't anything special, and the toppings are decent but can't save the nothing that is the soup base.
Another problem is the complete and utter lack of regular soy sauce. All they have available is the low sodium version. They obviously know that their product requires condiments because they give you a pile of them, so to not have regular soy sauce is baffling.
