You aren't wrong that the Sesame Inn in Mt. Lebanon is worse, I have also gone to it a couple times and it is hard to tell that it is the place, because of the quality difference.

Also one place to check out, is Number 1 Kitchen off of brownsville road next to the shop n save. It may not look like much being a small corner place, but it is the best cheap chinese food you will find (and even better than some more expensive places). Part of it is that it has been there for decades at this point, and what it lacks in looks, it makes up for in quality.
