Honestly the best ramen I've had personally in Vegas.
I appreciate a lighter broth than is typical in the US. Most ramen places overdo the umami and salt which leads to a really heavy flavor. Hashi aims to use fresh ingredients and keep the broth lighter. They make all their noodles in a machine up front and the owner has told us that he intends to tweak the noodles here and there as they find their identity in the LV ramen scene.
At 9 dollars a bowl that includes half a soft boiled egg, bamboo shoots, and chashu pork, Hashi is very reasonable and their portion sizing is excellent. Not too big, not too little. My only nitpick might be that there was a little too much onion and sometimes the noodles are kind of twisted together. I noticed the chef trying to loosen them up when he prepares an order.
I do have to mention that they seem to have some growing pains as tonkatsu wasn't available the first day we went, but we went another time and had it and it was very good. However, that day, the pork rice bowl wasn't ready because the rice was being made. I did get to try a mini version of it and the pork was slightly tough, but I'll withhold judgement until I try the full order.
They also have a spicy seasoning you can add that does add quite a kick to the flavor.
This will be our regular destination for when we want some ramen (though to be honest that isn't very often).
