Lunch in Brooklyn?
I like Rebar or Super Fine in Dumbo. In the Heights, Clark Street Diner is a good cheap lunch spot. If you want to go a little further, there are a lot more options.

I don't want to start a huge debate on the merits of Grimaldi's Pizza. But, IF you want to try Grimaldi's, you should get there right when they open (I think at 11:30 a.m.?) so you don't have to wait for a table. Also, Almondine in DUMBO is nice.

Siggy's Good Food at 76 Henry Street offers great sandwiches and salads--all organic and pretty resonably priced. http://www.siggysgoodfood.com/
Fascati's pizzeria at 80 Henry Street has the best pizza by the slice in the area.
