Too long; didn't read: excellent Thai food in a cool downtown Toronto spot. Plan ahead for long lines!
Atmosphere: basement restaurant on Duncan Street decorated reminisce of a beach bar in Thailand (dark woods, bright colours and dim lighting).
Staff and Service: we were seated quickly and felt well attended-to prior to seating - there's an expansive bar area where people frequently wait for their tables. However, I'll say that the table service was pretty terrible (sorry!). Our waitress came and went, never checked in on us, and never offered us water.
Food and Drink: amazing food and great prices. We started with the Spring Rolls ($8), and shared the 'Chef Nuit Pad Thai' ($15.50) and 'Gaeng Kiaw Wan' of green curry with shrimp ($18). Dishes are easily shared or enough for one - most of the curry dishes are served in a hollowed our coconut (although ours was not...). Either way, I can't see going wrong wit any menu item. Of note, the Paid Thai was unique - rather than a sweet tamarind sauce, it was flavoured with a peanut sauce base.
Overall impression: what the restaurant lacks in their service, they make up for with their food - would highly recommend Pai!
