It's this little hole in the wall in Vegas Chinatown, on the other side of the plaza from the Ranch 99 and next to the mini mall. Sort of a Taiwanese styled place so their food is prepared accordingly.
Their specialty beef noodle soup($7.50) here is really ridiculously good, on par if not better than the ones you'd find in LA. It's a perfect cure for whatever Vegas-induced ailments you may have come down with lol.
Cash only! But it's Vegas, you have cash, right? lol
