I stumbled across Niwa-Tei based on a fellow FB's friend foodie blog roll.
I don't really have much to say about this place. The décor is simple. The service is adequate (they greet / seat / serve you accordingly). I can't say I am impressed with the selection.
I did order a bowl of Tonkotsu ramen and it was like everything else: adequate. The broth was tasty and milky (but nothing truly spectacular). The meat was tasty and tender. The ramen was not chewy enough and tasted OK (instant noodle like). The portion was very small for the price. I was still hungry.
I would not return. I prefer Konnichiwa (go check out my review).
