My order today from GBK.
2 buffalo burgers (without the bun - this is replaced automatically with a decent sized green salad). I refuse the addition of coleslaw, relish and dressing.
The buffalo is from a biodynamic farm in the UK, organic and grass-fed. Buffalo is a leaner meat than beef - it is also higher in protein, vitamin B12, iron and omega-3 essential fatty acids.
I ordered a whole avocado, a few eggs and some sweet potato fries.
