Small little shop next to Sunfood market. It's in the same plaza as Pho Saigon 8 and BBQ King.
Probably my favorite place in town to get a Bahn Mi -- though there aren't many good choices in Las Vegas. It's quick and very easy. I usually get the House Special ($3.25)... it's pretty much a combo of the ham, meat, pate, veggies, etc.
The sandwiches are actually a bit on the thin side. There probably isn't enough meat or veggies inside but the total flavor is still decent. It'd be great if they gave more meat in the sandwiches but their bread is amazing. They make it fresh daily so it's never rock hard like some places.
Would recommend orders to go. It's a really tiny space so there aren't that many tables in there for you to eat.
