Wok & Roll has changed hands so many times it's hard to pin down the exact times that it's "good" or "bad". I went recently and had Mongolian beef. It was pretty good. Lots of beefy goodness which I like, lots of onion as well.
Some things that I've seen that I find a little perplexing.
I ordered Orange Chicken once - I saw them use a gallon of orange soda to make the sauce. Gross.
There was a span of a couple months where all I ordered was Vegetables Deluxe because it seemed "safe". I can tell you I never received it the same way twice. I find this odd. Simple substitution of vegetables is one thing. Completely different sauces are another.
They have a big vat of fried rice that is cooked who knows when and if you order fried rice, they basically reheat it. It tastes old and stale.
I would love to give it another chance, but I've already been fooled before.
