Sorry for the slow reply, just saw this. We've been a couple of times as we have a few vegan friends, it's very good. Menu tends to be 3 starters, 3 mains and 2 deserts but these are all changed out fairly frequently. Portions are large and as is often the case with vegan food, it's quite carb-heavy so leave plenty of room.
They're very good at vegan versions of non-vegan dishes, I've previously had "fried chicken" made from broccoli and jackfruit and my other half had "fish and chips" which involved battered seaweed-wrapped tofu. They're very creative and the range of flavours they can achieve within the limitations of veganism is very eye-opening for none-vegans like me. I'd certainly recommend it.
For vegan food in Sheff there's also BurgerLolz on Abbeydale Road, they do properly "loaded" vegan burgers and milkshakes, had a couple of good meals with veggie/vegan friends there too.
