I don't know what authentic Thai food is, but this was tasty and spicy with crisp vegetables and tender meats. The coconut chicken soup was above average, but the Thai Rama King was really special, with a blend of red curry and peanut paste. I'll warn you about the heat. I enjoy hot spicy, and the waitress cautioned me about "hot". I told her that I understood and did not want Thai Hot. "Hot" was borderline too hot for me, so you might try one heat level down from your norm. This isn't a criticism from me. I've had too many Thai dishes where they were obviously "cooking for the public" and created rather bland dishes. These were wonderful. Ordering was slow. The waterglass did not get refilled til near the end of the meal.
