When talking about burgers, IMHO a well-made Portobello mushroom burger blows all other types of vegetarian burgers out of the water. It's its own thing, not trying to imitate meat. They are common at higher-end burger restaurants in the UK — which has many vegans and vegetarians. But it would need to be cooked properly to be tasty: marinated beforehand and fried for a proper amount of time to drive off moisture and develop umami. And because of that you'll never find them at fast-food places.
