Just ordered a classic serving for a fix of potato plus a cold elderflower tea which was slightly sour but really helps to cleanse the palate especially for the type of food that a rosti is. I added truffle oil as well, although cant really tell that there was an add on. But the rosti was really great!! They quite perfectly balance the right amount of oil to use that it doesn't feel greasy at all. The serving was also generous. Would definitely be returning for more!!
