I've been to different Congee Queen's in Scarborough and while I do think the Sheppard/Kennedy location is slightly better in quality, having this location in the west end more than makes up for it.
My Congee Queen favourite, the spicy turnip cakes were crispy on the edges, but not as spicy as I expected. Not enough green onions and egg like in Scarbs.
The fried pork chop in sweet and sour sauce was good (but the best is at Maple Yip Seafood Restaurant in Scarborough) but this would suffice if that's what you're looking for.
The snow pea leaves in garlic sauce is the best choy dish ever. It's $14.95 but sooo worth it! Try it if you've never had it before.
The yeung chow fried rice is good, but I think House of Gourmet in Chinatown in downtown Toronto has the best so far.
Come here between 3-5pm and if you get something on their afternoon tea menu, you can get a drink for free. Go milk tea! The decor is super nice so all in all, worth the visit of you're in Mississauga!
