Harold's Meat + Three
If you work in Lower Manhattan, Harold's Meat + Three promises a classic American brunchy menu with a Southern flare. As far as sit-down lunch places go, it's pretty casual. Their "Hot Dog Du Jour" menu is a crowd favorite and an absolute must. And yes, they have avocado toast.
