These guys are very welcoming of visitors. Sim Go is awesome and is a great instructor... I've trained at his club a few times and will continue to train there when making visits to LV.
I had an opportunity to roll with him and a few other Black Belts there. It was quite a treat. He is super technical and very fast. Their BJJ is legit. His classes are super personable and you get tons of attention.
This is the place to be if you are a BJJ fanatic. I plan on visiting place frequently while when visiting LV and have the itch to train!!
