The value is one of the best. We usually come here for their seafood chow mein platters ($15, enough for 2 hungry people) - one of the best we've ever tried. We used to go to a Scarborough take-out spot for chow mein but Lee's is closer and a lot better. The taste has gone down a bit over the past couple of years - if you asked me to rate them 2 years ago, Lee's would get a 4 stars.
They also have nice lunch specials for 1 that taste pretty good and are good in value for under $10.
I recommend Lee's. The store itself isn't the prettiest but you come here for take-out - not dine-in.
