Lion City Restaurant
Lion City Restaurant has a number of diehard fans who proclaim it as the most authentic SMC restaurant around. The interior ambiance feels a little like Coconut Island in that it's simple, slightly underwhelming, and reminiscent of a small eating place in Asia. The Hainanese chicken rice is excellent, rivaling that of Phoenix restaurant, and the bak kut teh (pork rib in herbal tea - yes I'm serious) is quite close to the ones I've had in Singapore.
The owner is a Singaporean lady, which explains a lot of the "authentic" feel to all the food. Living in Markham as I do, I don't think it's worth the drive all the way to Mississauga when I have closer options that are almost as good, but this is a personal preference. This restaurant is a definite must-try for all those who live nearby or don't mind the drive. Try the fried kway teow too.
