In general, I find that plant alternatives in things that are saucy and will absorb the flavour are nearly indistinguishable or better than meat.

Good "Chicken" substitutes have become so good I'd rather have them over some god knows from where and what cutlett.

And there are veggie parties that are not meant to be meat like, but are delicious on an entirely different level.

The beyond, and such burgers are equally delicious though their price is spectacularly ridiculously high.

Still hard to find a non rubber veggie dog, though.

Their 60% number is maybe misleading. What it probably means is all their meal items are served separately so if they’re doing a beef roast with roasted potatoes, and steamed veggies, that’s 66% of those offerings are vegan. It’s hard to get a good metric for what that means without also considering things like which vegan options are high in complete proteins, do all meals have good and varied options(if it’s the same vegan soup and salad bar for all three meals that gets old quickly) and if most of the vegan options are essentially side dishes for meat forward dishes or something that stands out as it’s own thing.

Admittedly it can be tough, because there’s so many groups to support. Some need vegan, gluten free, halal, dairy free, no pork, no beef, plus less common allergies. It’s hard to accommodate everything with dishes that are still going to appeal to people that don’t have those restrictions, or significantly increasing costs to accommodate 10% of your customer base.
