Bubby's in DUMBO (Brooklyn) has a bunch of HID fluorescents hanging around for its plants. I helpfully pointed this out to my DW as an example of how grow lights can co-exist with hip design; her reply was, "I think they're ugly." Alas.

There's also a plant store/cafe in the flower district (6th. Ave, 26-27th street I think) that I think is very cool; the tables are set around groups of plants for sale, and the even have wall-hanging fountains filled with ferns, bromeliads, etc. on the walls!
