For 5 people, we ordered the 4 person meal with an additional appetizer and green curry.
Everything is very well executed. There was plenty of coconut rice to go around and feed 5 people comfortably. All the dishes were colourful, flavourful and a good size for 4 people. The basil beef was the most popular, as was the Red Curry. They were nice enough to supply one more dessert for a fifth person even though it was a four-person meal.
The only complaint we have is that is was very cold in the restaurant, but we did go on one of the coldest days of the year...
Also, the service is excellent.
