As to the op's question. I have been surrounded by vegetarians my whole adult life (all 30 years of it). My first husband was a vegetarian as was DH (though he eats fish nowadays). DS became a vegetarian a couple of years ago so eat a an 80% vegetarian diet by virtue of living with two of them. We have tried the odd vegan week and I I can hand on heart say I would never become either a vegetarian let alone a vegan
Almost without exception restaurant meals with meat are much much nicer than most vegetarian ones, let alone vegan ones. At home this is not really true as I cook almost no meat so don't know what to do with it much anymore, if i do cook it is is never great.
However compared to the things I used to eat as a child (stews,roasts, steak, casseroles etc) the food I have eaten over the last 30 years is generally blander and less tasty. This is because it is vegetarian not because DH and I can't cook, we can.
I must have tried 100 different veggie burger recipies over the years in a vain attempt to find a delicious one and absolutely none of them, even a decent one is a patch on a really good burger. Same with curries and stews, they are all always much nicer with meat than with just vegetables.
Even pasta dishes are generally better with some meat in, though with the addition of parmesan (not veggie though) I find these bearable
I am not overly keen on most fish, except mackerel and salmon so could easily give that up though!
