I can't comment at all on authenticity (and don't think that matters every time), but a great lunch. I will say it's completely bananas, and I avoided it for a while because the line is just unreasonable, but at a quieter time it's pretty fantastic. Highly recommended the fish, and the salsa bar is a magical little addition. Mango particularly great with the fish. Super filling and worth the price in my mind (especially given it's King West).
