I don't have much to add about atmosphere---it's a tiny space in a strip mall and you have to wait a while. It gets quite a big crowd.
Overall it didn't quite live up to my hopes, but it was still solid. I spent a few weeks in Singapore about 2 years ago, and had even had laksa up in Melaka, Malaysia. Ever since then I've had vague hopes of having laksa that good again, but it never happens. This is as close as I've come in North America, but it wasn't quite right. The mix of stuff in the laksa was just right---noodles, tofu skin, fishballs---but the broth wasn't what I had hoped. I tasted a lot of curry and coconut, but my favorite laksas in Singapore and Malaysia all had a much richer spice mix and depth of flavor that was really missing here. Oh well.
If I went again, I'd probably try the Hokkien Mee---it looked really good on other people's plates, and the size of the fire under some woks in the kitchen looked quite promising.
