Additional $2 for the Tom yum soup add-on I think. It was not very worth it for. It was way too tart for me but I think come people like it that way. The pad thai portion was huge! I struggled to finish it. The Thai stall which was there before this new one at JEM was wayyyy better. This wasn't bad. Average. There were two chilli sauces but they were not very different. Both were quite sour. The Thai stall at Westgate has a similar way of providing two chilli sauces but they are both very different and delicious. Around $5.50 for the pad Thai.
