Chili Chicken on rice; can't beat it for a quick, tasty lunch with a spicy kick.
Perennial choice is China Garden on N-E corner of Derry & Airport Rd.
New option is The Ming Room on Mississauga Rd just south of ErinMills Pkwy.
Check 'em out; both are worth a try.
p.s - What the heck is General TSO Chicken?
