One of the world's top restaurants is ditching meat. Here's what could go wrong

Earlier this week, Eleven Madison Park's chef and owner Daniel Humm made an unexpected announcement: When the famed New York City restaurant reopens its doors next month, meat will be off the menu.

It might seem like the perfect time to get people on board with an all-vegan menu. Plant-based proteins are as popular as ever. Impossible Foods and Beyond Meat (BYND), which sell alternatives to meat designed to look, taste and cook like the real thing, have expanded massively in grocery stores and struck major deals with big food companies and restaurant chains. Last month, the food site Epicurious said it would stop publishing beef recipes, noting that production of the meat emits harmful greenhouse gases. But even in this climate, abandoning meat entirely is a big deal — and sticking with the menu could be an even more difficult proposition.
