This place is hands down my favourite when it comes to eating Chinese food: it's fast, it's cheap and it's good. There are so many options, that it doesn't matter what you're feeling for and who you're with, there will be something on the menu that will satisfy most tastebuds. My personal favourite: their Yeung Chow fried rice. I've tried this fried rice many a place, and there is nowhere better than here. Seriously.
As mentioned by nearly everyone else, the line gets long during lunch, especially on weekends, so either time your meal well or get ready to wait (but it'll be worth it, so just sit tight!)
