Looks like a great week of eating!
Han - I like Han, but confirm it’s open Christmas Day. It’s very low key, so tbh if it were me, I’d opt for K-bbq or Dim sum just for the fun of the overall experience on Christmas – I know you’re coming from LA/SF, but I’ve eaten both there and I still prefer NYC (except dim sum for which SF would win over Manhattan - but maybe not Bk or Flushing).
Zaytinya - Since you’ve been to the DC one, maybe go somewhere more New York than that for a meal. It is in a swanky new Ritz, but been there done that, right?
Veranda - I have not been, but George Mendes is solid. Still, the menu seems pretty generic high end modern American-ish. I sent friends to Popular at the Public downtown a few weeks ago: they’ve been raving about it ever since and even went back for their anniversary this weekend. It’s Peruvian-leaning, so might be different enough than other stuff on your list. (Diagonally across town, but that’s why we have cabs!)
Soothr vs SuperTaste - You said upthread that SuperTaste has great memories, so I think this is not really a question.
CiSiamo - I haven’t been yet but hard to go wrong with the Danny Meyer formula. If you don’t get a rez, Marta is excellent (and has great pizza to boot).
Empellon - I like his food a lot. That said, you really want modern Mexican coming from LA? Also that’s a lot of fancy places in a short time. (I’d probably send friends to get a couple of unda chicken kathi rolls at Kati Roll Company and then to spend the rest of the lunch $ at Lady M or Royce around the corner after. Or something else casual-delicious and/or more New York-y.)
Breakfasts - I hope you’ve got a bodega or street cart BEC+coffee factored in somewhere, and a few bagel stops!
Pizza - @vinouspleasure gave a few suggestions upthread. Which is your 10-person pizza meal? Rubisrosa is great, but I don’t know about a 10-person rez. I will also throw out (at risk of being trashed by everyone else) that John’s in Times Sq or John’s on Bleecker (unrelated) are both a solid choice for that style and size of group.
