It can be hit and miss from my experience as well. We have a bar and grill place that has a black bean burger and the fucking patty is 1/2 lb and an inch thick. The burger tastes good but it's way too much bean and it ends up being a chore to eat. We have a fast food place that has a black bean burger that is pretty thin but you get a lot of veggies on it and it is all pretty balanced. We have a local hipstery joint similar to the meme posted that has amazing food all around but they have a beyond burger and a black bean burger and it's actually nice to have that option but they also always have like 3 other vegan options.
