Brunch is a natural for a venue whose first name denotes a street bar--a natural disaster, that is. But Greenville Bar and Grill, a white-tablecloth retrofit of a once gunked and grimed watering hole that's been hovering around Greenville Avenue since 1933, beats the odds. Greenville's eggs Benedict is like no other. Slathered in a smooth, tangy hollandaise sauce, the fluffy and plump poached egg sits on a chewy sheet of Canadian bacon bedded down on a muffin so tender and pliant that it disintegrates as soon as it hits the mouth (and it isn't one of those watery, predigested muffins either). Perhaps even more amazing--and rare in the world of Benedicts--is that this version is actually hot through and through. Not cool, not warm, not piping hot hollandaise over a chilled egg with icy whites and golf ball-hard yolks, but hot, from muffin bottom to hollandaise tarp. There's no rubbery egg white or watery poach discharge either--grave hazards after a night of serious drinking or a morning of serious molten brimstone lingo. Omelettes are constructed with the same exacting care. They're fluffy and light, almost like little soufflés. Even the fruit plate--typically a thoughtless ensemble starring the mealy and the insipid--is riddled with the plump, the bright and the fresh. Greenville Bar and Grill's brunch is so good, you'll find yourself forgetting about that dog-hair remedy you're convinced you need to help the eggs and the head whir stay down. But there's plenty of that behind the handsome bar if your memory is extra sharp.
