2nd Momofuku Ssam Bar & Vandaag.

I think Ssam has more variety than just 4-5 kinds. I've had shiitake mushrooms, fennel, Romanesco cauliflower, beets, tokyo turnips, carrots, cucumbers, celery all on the same pickle plate.

Is it really affogato if it's hot chocolate over gelato? Do you still get whipped cream on top?

Where's the Dutch? Minetta Tavern, Spotted Pig, and the Dutch all received A- reviews for their brunches this year, but I only see the former two on the list.

I find all Chinese restaurants to be a bit of a crap shoot. Chefs come and go all of the time, and perhaps the "B team" chef was on duty last night. Or as my mother sometimes said, maybe he was fighting with his girlfriend. :)

Slutty pancakes
Glazed maple doughnuts
Sliders with carmelized onions

A lot of people like the Blisters on My Sisters, but I thought it was only OK (I had the duck version).

I also thought the Wontons in Red Oil much tastier at Legend than other restaurants. The "wontons" at Szechuan Gourmet use regular dumpling skin, pasted together, yuck! However, SG's cumin lamb is definitely better and more flavorful.

Also I actually like the Dan Dan Noodles at Legend more than other places, because they cut the noodles shorter, so it is easier to eat and the sauce gets more evenly distributed.

I'd double check actually regarding inoteca LES, inoteca Gramercy, and corsino, as I think their reservation policies may have changed.

Is this for a weekday? Weekend? Are you wiling to eat on the earlier side or the later side?

Craft and Blue Hill are pretty hard to get into if you're booking for a week or two from now.

I would recommend Mas Farmhouse or Hearth.

Cookshop is showing as booked until 2pm on OpenTable right now (they leave a fair amount of tables for walk-in patrons).

Jane has only 11am and 1:30pm for tables of 5; also they serve Saturday lunch with a few breakfast items thrown in, if that matters to you.

I would look into:
Locanda Verde - I've seen strollers in there and it's a hotel restaurant, so presumably they have a high chair, call for availability
Perilla - showing 12pm availability on OT right now, the staff are very sweet and I believe they have 2 high chairs
Hundred Acres - same people who do Cookshop, has 12pm or 1:30pm right now
Landmarc Tribeca or Time Warner Center - they only take reservations for parties of 6 and I'm not sure if your young one "counts"
Tertulia - the brunch service is pretty new, saw some kids in there a few weeks ago
Lure - the food isn't amazing (just good) but the space is fairly large, but I'm not sure if I've seen kids in there before. The burger is excellent though.

Non-brunch lunch options:
Lupa has 12:45 on OT.
Otto is pretty open.
As is Po on OpenTable.

Try Zibetto Espresso Bar at 1385 6th Ave (between 56th and 57th). Excellent espresso, no seating.

I'd add on maybe some suggestions on where to go near the AMNH and MoMA.

Too bad the OJ is the only good thing I've ever had at Norma's!

I nominate the $8 pretzel at the Standard Biergarten. It's huge but not big enough to justify the price tag when compared to Sigmund or Cafe Katja.
