Excellent food; noisy, casual ambiance - sometimes abysmally slow service so expect a longer than normal dinner and having to potentially flag your waiter down. Do it with a smile for your own nerves.
Usually it's a 40 min + wait and I wouldn't suggest large groups attempt to go here without a reservation.
The food is reliably good Thai from the current masters of Thai food in Toronto. Ambiance is nicer than Sukhothai on Wellington and equidistant from the financial district.
