"You’ll get a good amount of egg noodles in a regular bowl; they’re thin and firm, which is pretty standard and authentic for a casual dish. There’s also plenty of broth, but I’m not a big fan of too much broth—I’m more of a #extranoodles person (they offer extra noodles as an add-on, so you can customize your bowl while keeping it authentic to traditional Japanese ramen).
The portion sizes aren't overly generous, but they seem to be trying to be cost-effective given that the place wasn’t packed. However, there are several types of noodles to choose from when you dine in, even though it was quiet (it's South Dakota, after all—we love our Culver's and Sickies’ Mac n’ Cheese bowls).
They offer a nice selection of drinks, including some Asian options that are definitely worth trying over a soda. Ramen Fuji competes well with Sora Ramen in Las Vegas, which is popular among Asian executives for lunch or dinner. If you stick to a bowl and one side, without a drink, you might keep your bill under $20. But if you’re someone who knows their ramen, you’re likely to spend over that.
Overall, it’s a niche, hole-in-the-wall kind of place. I recommend trying it at least once—impress your friends or drop by when you crave a hot bowl of authentic ramen in Sioux Falls. If you’re visiting the area, definitely stop by, enjoy the peaceful atmosphere, and savor the food. Enjoy!"
