I decided to give this place a go despite it's fairly low rating as I had a long day and this place was just at the hotel I stayed (Treasure Island).
I went with the special (combination) beef noodle soup (pho) after being recommended by the waiter. He explained that they have recently replaced the chef and the pho had gone back to its original/traditional recipe.
I was pleasantly surprised as the soup was of generous portion, authentic, very flavorful served with fresh bean sprouts, basil leaves and green chilis.
Definitely the best Asian dish I've had at the Strip and will definitely go back for more.
One point to note, service may be a tad slow but once the order has been taken, the food was served less than 5 mins, it's well worth it!
