Quick (short version) story: Friends and I went to vegas. One friend's parents called in an order 24 hours in advance, and said friend was not allowed to pack very much in his suitcase because he had to have enough room for all of the bread purchased from this bakery.
This is definitely not a place any las vegas partygoer would be able to find...because it is about 20 minutes? off the strip.
Decided to accompany my friend over to this bakery because there was so much hype surrounding his order...the staff here are quite nice and will take the time to explain what their most popular breads are and what's in them (even though ingredients are all listed on the packaging).
I got the "siobao" which is very similar to a cha shu pork bun that you could get from dim sum spots, but larger and not necessarily with that same style of bbq pork.
Also tried a red bean bread and that was tasty as well.
Quick Tip:
1) Cash Only
2) Located next to a seafood supermarket
3) Their most popular breads appear to be immediately to the left, on top of the refrigerators
