We have a loving hut nearby (Brighton, UK), and I can't say that I was particularly taken with the menu. I'm not even sure if I'd class it as food and I'm a champion for veganism!
The quality of their branches doesn’t seem to be consistent. For instance, they have a branch in Palo Alto that is a cafe where they reheat food prepared in advance. The food in this branch is kind of meh. I guess that is one of the reasons I didn’t fell compelled (yet) to go to any branch in London (where I leave now). There’s good (and cheap) vegetarian food everywhere in London!
