This was a fun and different thing to do in Vegas. There was a surprisingly large amount of food for sale. Many of the desserts were $2 per serving, Thai iced tea was $2 and Roti was $1 each. We bought 5 limes for $1 and a large bunch of basil (I think it was $1). They also had lemongrass. Everyone working the tables were friendly and helped explain what everything was since I didn't recognize most things. Several did tell me to come earlier the next time, as many things were already gone. I do wish there had been more tables with chairs - we had to sit on a curb to eat until a table came available. I did take a quick look into the temple, which I'd never been in, and I felt very welcomed.
One tip I'll give -- the pad thai took about 30 min + after ordering (very popular! and very good), so next time I'll be putting my order in there first and then check out the rest.
