Shokku Ramen
This Japanese style Ramen spot is located in China town of Las Vegas which is 5 to 10 minutes away from Treasure Island, Wynn and Resorts World.
They also have other items than Ramen on the menu. It was pricey for my Vegetarian Ramen but it was tasty and visually appealing.
I didn't get to try the Dragon Ball inspired food item, but it looked nice. If you don't mind the Anime theme and love Ramen, you should definitely check this place out.
