I have it on the authority of a Kyushu native that the only authentic Hakata-style ramen in Niigata is to be found at Ippudo (一風堂). It certainly was tasty. Hakata ramen originated in Fukuoka City in either 1941 or '42 at the open-air stall 三馬路 (Mimaji? Mibaro?), operated by one Morii Kentaro. The ramen is characterised by a pork-based soup and thin, straight noodles.
