Chilli chicken.
Now, I've had chili chicken before at other places (Lee's Wok, Tangerine, China Cottage, Wanlees, etc), but the one at Federick is just at another level. Right amount of spice, but the sauce is what really blows it away. I don't know what they put in it, but it keeps bringing me back. If you go for the lunch special, it's only around 6.75 after tax and you get a free can of pop.
Overall, 5 stars for the chili chicken (sadly that's the only thing I've gotten at Federick - It's just too good)
