Dumbo has the best small park for viewing Manhattan. There is plenty of food to eat on grassy slopes. The views are framed by the Broolyn and Manhattan bridges. There are places for kids to play and a carousel. This is why I gave Dumbo five stars.
The food court next to the park would also get five stars. There is a huge variety of open air food stalls. I had some of the best oysters I've had in a long time and everyone seemed to be happily eating the food of their choice.
It might also get five stars for the many art galleries, but I was there on Sunday and only a few were open. I plan to go back on a Saturday to see them.
The neighborhood buildings are non-descript commercial buildings. Not much to look at.
Dumbo is next to Brooklyn Heights so both can be visited in a long morning or afternoon.
Suggestion. Stroll Brooklyn Heights on a weekend morning and hit Dumbo for lunch.
