This is a fantastic lunch stop near UNLV. So far I've had their banh mi, which tastes great, and is very filling for the price. (At the time of this review, a house special banh mi is $3.50!!) I'd order two if I thought I could finish it.
I see practically zero downsides to this place. Great location (right off the crosswalk), outdoor seating, and simple / tasty food for under $5. (If you want a big bowl of pho, you're going to pay around $7-8, but that's still great for lunch.)
Seriously, check this place out. This is a local business that I'd love to see succeed.
