My partner and I come to Komol at least twice a week. You won't find authentic Thai better anywhere else in Vegas. I usually order shrimp and chicken Pad Thai with the spice turned up. Soooo good.
If you've not tried the homemade coconut ice cream with sticky rice, you're missing out. Komol blows Lotus of Siam out of the water, IMO, and always a much shorter wait.
The service is pretty stellar too!
