My 5 star rating is based off of eating the Thai food in the treasure coast. Thai Food Express has the closest to authentic food in the area. A major plus is that they offer Thai noodle soups like pork soup with a clear broth or duck soup with a brown broth. I have had a very hard time finding that anywhere else. The soup is totally authentic, and I was relieved that at least there was one place to go to to relieve my cravings for duck soup. They do deliver, but you need to stop by and pick up a menu to do so. I was unable to find a menu online. The lunch specials are pretty good. Overall, this is my favorite Thai restaurant in Port Saint Lucie so far. I know everyone likes Spice Thai, and I'm not saying that they're bad. If you like it, then I encourage you to keep eating there, since it was a cute restaurant and the owners were very nice. However, Spice Thai is far from an authentic Thai restaurant. The panang curry was almost white, instead of the red color which it should be, and the soup had only American veggies in it. As a Thai person, I prefer things closer to what I ate back in LA, so for now, I'll be getting all my Thai food at Thai Food Express.
