the botanical gardens is not far. personally, I dont enjoy looking at flowers, but some might enjoy it, and perhaps find it to be a fun activity. prospect park and prospect park zoo are not far. you can sit outside 770 and try to gues the nationality of everyone who passes through the doors. hatzlacha.
Basil restaurant (pizza and dairy). Best kosher pizza this side of Jerusalem (I like the one with asparagus). And pricey enough to make a good impression without busting the budget. Other entrees excellent.
