Landmarc at TWC is kid-friendly. However, it may be really crowded at 8, and it does not take reservation. If you go early to put your name on the waitlist, then you can shop around TWC and wait until they call you.
Depends how many kids, how old, etc. I like Gabriela's and it's very kid-friendly. Gennaro is kid-friendly, but you may have to wait because they don't take reservations. The city should be pretty empty this weekend so you might have more luck.
