Vegetarian in Brooklyn for one night

Hello!

I’m flying in on a Tuesday at 2 pm to LGA, check into my hotel in Williamsburg (southern end) at 3 pm and have that night to explore!

I was thinking about going to the botanical garden but I’m not sure what else to do. I contemplated going over to Manhattan but am overwhelmed by the options. Would it be worth renting a bike and going to Central Park? I would also be interested in the 9/11 memorial though I’m concerned that may be extremely depressing and perhaps I should save it for another trip. Or should I focus my very limited time in Brooklyn?

I would like a recommendation for coffee the next morning (oat milk lattes) as I head to Barclay stadium for a concert. I will be camping out all day so any food recs nearby would be great too!

Then Thursday morning I want to get breakfast and explore a little before my flight at 2 pm. I’m thinking I could go walk the Brooklyn Bridge that morning.

I would love to see some cute shops, art, beautiful natural spaces, cool architecture. I am a foodie and love a good view.

Thanks so much for any advice. Also, is it safe for me to be walking around by myself when it get later in the evening or should I be taking an Uber?
