Someone asked for me to expand on Balthazar's breakfast. It is an interesting topic because B'zar is one of the fancier non-hotel restaurants that serves breakfast every morning (it opens at 7:30).
I had (1) eggs Florentine, which was good, not great; (2) English breakfast (which I love and always get if its on the menu) which was not so great; and (3) poached eggs with toast and homefries, which was ok.
Balthazar opens at 7:30 and closes at 1:30 or 2:00 am. I jokingly described Balthazar as SoHo's Denny's, and the locals agreed there is much truth to that: the place is as full-service a restaurant as any Greek diner, but much more expensive and serious about food, obviously. It is very comfortable, especially at off hours. It's nuts late in the b'fast hours, at lunch, and after work through dinner. It is the anchor of the neighborhood and filled with regulars.
I most enjoyed it after midnight (NY time). The hippest 'hood in the city that never sleeps is pretty damn quiet on a Tuesday at midnight, and only one or two Chinatown places worth visiting are even opened past 11. Interesting that we have more late night asian options (though a much smaller Chinatown).
Back to Balthazar: I'm a fan of poached eggs, but Balthazar's were consistently marred by the use of way too much vinegar in the water (a well-known trick to keep the whites from drifting). Some were like pickled eggs. The eggs themselves, massive organic and fresh, were obviously tops, produce-wise. The Florentine treatment, which presumably started with a sauce base of Hollandaise was good. The English breakfast sported lots of too-firm beans that seem to be the same ones used for the cassoulet, which struck me as wrong. Bacon/rashers was pretty good, and brat-like sausage (only one kind, no black and white pudding) was a dry letdown. Based on the waiter's praise, I really expected this to be a superb English b'fast. However, I honestly have had better "Irish" b'fast (same thing) here at Fitzer's Pub and at Ginger's Ale House. Of course, the pubs use Heinz canned beans, which a place like B'zar would never do, but I'd actually prefer it.
Honestly, the oysters I had were superb and the shucker is a genius. Pristine, separated from the shell, completely intact, no liquor lost, and very good mignonette. Fries are very, very good, though I would give the edge to Hopleaf here. I was disappointed by the mayo, which did not appear to be house made. I could be wrong, but it wasn't great. Only Belgian beer on tap is Stella. Other tap choices are things such as Bud light etc. I'd love to get deeper into the fruits de mer at Balthazar. Every thing looked great, and reminded me of places in the South of France.
PS, I can't overemphasize how nothing Mercer Kitchen was for me. My cod and potato cake, which I took to be a spin on similar Portuguese/Spanish bacalao dishes was awful. Here's the recipe, as I reverse-engineered it:
1 large potato -- boil 'till almost soft;
1 cod fillet -- boil 'till defrosted
Mash all ingredients with fork and loosely combine;
Form into a patty and place under broiler
Serve with great flourish.
