I've been here on two occasions now and find Lion City a nice simple place to have some Malaysia and Singapore fare. However some things can be a bit hit or miss.
The shrimp wonton was a great appetizer to start with. There's plenty of juicy meat and shrimp in the filling and skin is nice and crispy.
The curry laksa was excellent. The curry had a great kick of spice to it and the coconut milk. There was various toppings of chicken, fish cakes, shrimp, and fried tofu. It's a pretty loaded dish and I'd recommend this.
The Hainan chicken is also a classic. The rice is excellent: it was moist and flavored. The chicken was really tender and so was the chicken breast. The addition of the three sauces really completes this dish and enhances it. I really enjoyed all three of them - the ginger garlic was my favourite, the sambal was sweet and spicy and the soy based sauce was also sweet and savory.
The chicken curry with their roti was a big disappointment however. The flavor of the curry lacked a certain depth to it (as if there wasn't enough onion or garlic) and the chicken was so so. The roti appeared to be the frozen variety and was rather hard and stale. The worst part was that the curry was on the expensive side and it didn't include any rice or roti.
Service can be a bit lacking at times as they're a bit understaffed but overall it's still a great place for South East Asian food in Mississauga!
