If you walk too quickly on Bloor, you will miss the entrance to Sabai Sabai. It's located right underneath the much more noticeable Firkin on Bloor. Find the bright yellow mural going up to Firkin and then promptly ignore it to go downstairs instead.
Torn between noodle items, our server recommended the mee kati noodles for a more unique menu choice but advised the street style noodles would be more filling. I was hungry, so I got the street style tossed noodles ($13) which is their version of pad thai. It came on a large plate with a heap of rice noodles, chicken, beansprouts in the center. The noodles had been tossed in a light tamarind sauce, which gave a nice sour tang and a squeeze of lime brightened up the dish. Delicious and filling, I devoured the whole dish but didn't feel too greasy or heavy afterwards. My companions like their choices also, so I'm sure you will find something you like
Our server was really personable and attentive. He answered questions, gave recommendations, checked on us periodically and made our lunch more pleasant by being patient and friendly. Great job on the service!
