Landmarc isn't really a steak place, and it doesn't really bill itself as one. It's more an "American bistro." As such, they have steak which is very good, but more a bistro steak than a steakhouse steak. The food as a whole there is good: it's just kind of ordinary and unexciting. Worth eating if you're there, but not worth a big-deal trip.
Prices are moderate. (But to me this is the kind of place where the food is unexciting enough that it just isn't quite worth paying for, if you know what I mean.) The wine program is spectacular, though -- very very gentle markup.
They're about to open a branch in the Time Warner Center.
