Do not come here.
I was in vegas for our family trip and my family always insists on getting Vietnamese food, despite all the other food to choose from in vegas. We yelped a pho place, but it was closed down so we found ourselves at Pho Bosa.
When we entered the restaurant we were rudely greeted and said we would have to wait for a seat in their small and dirty restaurant. When we were seated the waitress was also rude to us as well. To make things worse, they have these signs on their walls that basically states you are not in a fast food restaurant so be patient for your food. Obviously, if you are at a restaurant there will be a wait and it's pretty unnecessary for them to post that sign.
I ordered bun bo hue which was decent for vegas.
The gentleman that came to bus our tables after we ate and he asked me if I like my bun bo hue with a native tone and it confused me for a bit because he didn't look Vietnamese. In any case, wish we encountered him earlier because he was friendlier than the rest of the people that work there.
