I'm trying to find authentic Singapore cuisine. I've tried tons of places. Only good one I had was Satay Ria at Market Village but they closed down =(
I second Lion City.
I find it's pretty authentic. The chendol last time was kinda mushy though :p)
I believe it's family owned, and their chicken rice is supposed to be fantastic (as drooled over by my Singapore born friend
Oh and yah, they've got the chili crab.
I love coconut curry...
I agree with all the recommendations for Lion City. It's about as close to authentic S'pore food in Toronto. I'm a regular there, but I've never ordered the black pepper crab, so I can't really comment. It is indeed family-owned with a Singaporean chef. All the dishes are pretty solid... the fish in banana leaf is really good as well as the chicken rice.
Whether it is worth the drive, is up to you...
