For this price there's no complaints. The impressive part is the thickness of the tongues, it's about twice as thick as normal, and the portion is quite something. On top of that, it's very fragrant from the lashings of oil and the spring onion. If you cook it perfectly, it comes with a good crunch and was very meaty.
IF. Not sure why but apart from the first 2 pieces, the others all had one pesky part near the middle of the grill that simply refuses to be cooked. Since you can't turn or you risk all of the spring onions falling out, you have to keep waiting for that part to be cooked and it was thus very easy to overcook. It's really difficult to cook it perfectly without turning, even for someone who's quite experienced with tongue if I say so myself ;)
Further, the spring onions which drop down eventually becomes burnt and sticks to the grill, so that's another hassle on its own.
Without the discount this is too much trouble, esp if you're someone who's not into tongue in the first place
