This establishment serves off-brand freezer food, poorly stored, old, and frost burnt, barely cooked, the sesame beef was slimy and rubbery on the outside and inside (we asked if they were able to prepare it crispy, they seemed confused and indicated it could only be made one way - first red flag, even most freezer food can be prepared more, or less crispy), the crab rangoons tasted like they were constructed from a powdered cheesecake mix with tap water and crab added, and they offered sauces with the food, that were so poor, I just... I can't even begin to imagine where they came from, for them to taste so chemical, and horrible. The filler chemicals in personal lubricant is the only thing I can think of that comes close, instead of sugars and starches, they are using some kind of low grade, cheap petroleum byproduct. The sauce (even warmed) broke into chunks, so I tipped it upside down - it came out like a jello mold.
It was either not properly prepared in a way the chemical ingredients could tolerate, and had become toxic from overheating (the smells was bitter and rancid, like old plastic lotion bottles), or at the very least it was old and dehydrated from overheating. Since the meat all smelled similarly old, I'm guessing the sauces had been sitting all week long, like the rest of the food.
Save your money and buy some egg rolls from the local supermarket.. they'll be the same thing anyway, or treat yourself to the mid-range or top shelf frozen fare, and you'll be eating gourmet compared to this.
Normally I'd say we might just be spoiled from cooking authentic and recreated american-style chinese food at home, but we also order out enough to know what's normal and what isn't - this was unusually poor quality food.
