Good food, but a bit pricey. You kind of pay for the modernish look. I ordered a pumpkin soup and a shrimp dish. I don't think the size of the plates were too small, served the two of us perfectly. But I really think that almost $15 for a shrimp plate is a bit high.
I don't think they serve as good as their prices think - I was best served in a lower-priced spadina thai restaurant - and they even charge you for the tea you drink.
I don't think Green Mango is a very good deal. Maybe for a romantic occasion, or business.
