Tried their pad thai to gauge the food. Pretty good flavours though a bit on the salty side (was still very thirsty hours later!).
Went back a second time and tried two curries -- green and the off menu panang curry. Both were just terrible. Green curry was watered down and had very little flavour. Panang curry had frozen peas and carrots instead of fresh vegetables and was really really sweet.
I would say that their attentative service and the loyal clientele that enjoys canadianized thai food keep it in business.
