I lived in Vegas 4 years ago unfortunately Nielsen's didnt exist the time I was living here, the only custard place I knew of was Sheridens which is now closed. I use to work at a yogurt shop and yes I know Nielsens is not yogurt but half of what makes the best tasting yogurt/custard is maintenance (cleaning the machine everyday!) Both times I was here I have witnessed them clean there machines, and trust me it is no easy task! But it was nice to see that they are diligent about it. The place is nice and clean, I love the atmosphere lots of nostalgic memorabilia . The custard in itself is so delicious! I just get mine flavored Vanilla with Almonds... YUMMMM! The prices are also reasonable and the staff is great.
