There are two broad types of Thai restaurants in Toronto. Those where the chicken is fatty and tendony, and those where the chicken is fatless and tendonless. Bangkok Paradise is one of the latter. The green curry chicken is great, and all of the dishes are quite reliably good.
The decor is not great, however, so if you can get take-out or delivery, all the better. The lunch specials are very cheap and nice; you can call ahead and pick up your lunch combo quick.
