My family and I were really excited to try Nishikawa but were extremely disappointed. We came in around 5:30 on a Sunday night and were sat a table for 2, despite having 3 people instead of being seated at a table for 4 because the "dinner rush" was coming -- this would've been fine except the waitress was rude in saying so, and there was a couple that had just been seated in a corner booth suited for 4?
My aunt ordered the vegetarian ramen, which was extremely salty and the "vegetables" that came with it were sprouts, onions and corn. We asked to sub one of the "vegetables" for spinach and was told it wouldn't be possible.
The saving grace of the tonkatsu ramen was that the spice level was actually decently spicy. Although the ramen came with straight noodles and a hard boiled egg -- no traditional ramen shop would ever. Additionally, to add maybe 2 tablespoons of plain corn (not buttered, salted or anything) was $1.50!
Even the customer service was poor. We watched a family of 5 come in, and the waitress that greeted us told them "We don't have any tables right now." and then walked away -- didn't ask if they wanted to wait for a table or anything.
Would maybe give them another chance, and would definitely make sure to have the curved noodles and a soft boiled egg.
