I've only just visited for the first time last night but I'm already hooked. If you crave authentic Thai food this is your joint (and by "authentic" I mean spicy as hell!). The folks here give new meaning to "Thai spicy" so if that's your thing, look no further (it's definitely MY thing and therefore probably one of the reasons I liked this place so much). The preparations are fresh and flavorful and the service is exceptionally warm, pleasant and attentive. A final word of warning about the spice level: TRUST them when they warn you about how authentic their spice levels are. I'm usually a 10 out of 10 on the spice meter but I went with 7 to be safe and it nearly blew my head off. Nonetheless, the food is excellent, I'd say Top 1 or 2 Thai meals I've ever had in Pittsburgh (and I've had a lot!!)
