There are several postings on this board about the street food place under the bridge on East Broadway that kept talking about the "green sandwich". So I stopped by today and tried one. I didn't really like it, not sure what the hype was about. Sesame bread was not very good, fairly bland and the greens themselves were okay, but overall I thought it was very bland.
I'd much rather eat the sandwich at the Dumpling House, which is excellent.
