Flavourless generic meat, probably from frozen patties. The half pound burger consists of two quarter pound flat disks which is not nearly as good. No sear on the burger so it was a pale brown colour and all the juices leaked into the bun. They poured on the mustard - it's all I could taste. The bun didn't stand up to the burger and fell apart into a soggy mess by the third bite. The sliced onions were from the outer papery part of the onion. And to top it off despite the burger having no flavour at all, I burped up garlic for hours afterwards. Disappointing to say the least. Note: they don't take Visa.
