Question about LANDMARC (Tribeca)
I don't find their 2-tops to be any closer than anywhere else at that price point, though the ground level 2-tops are pretty tight. You should have a little more wriggle room upstairs, and in my experience it tends to be quieter. The tables are a little small - nothing like Kefi's postage stamp-sized 2-tops though - but again that's pretty much standard with Manhattan real estate...
Don't know if I'd say "really uncomfortable" though during very busy times it can get a bit loud and crowded... usually it's worth it.
Best thing to do would be to go during non-peak hours... they serve straight through from lunch to dinner. Also, in non-peak you might be able to get a bigger table to yourself.
Good luck & Enjoy!
