Oiistar is serving up some of the best noodles in Chicago, thanks to one very fancy piece of machinery: a Yamato noodle-making machine that clocks in about $65,000. The unique flavors that make the noodles really pop, though, are the invention of owner Sunny Yim. Indian-spiced ramen, classic tonkotsu ramen, and flavorful vegetarian options dot the menu. If you’re still buying ramen for 4 for a dollar, it’s time to upgrade your culinary choices.
