There is a soup kiosk on W. Broadway between Prince and Spring, that I've had my eye on for a month or so as a promising spot to get some lunch. I tried it today and was pretty disappointed. I got the "Moroccan Lamb Stew" (which was not, oddly, a tagine), which turned out to be a textbook example of the fact that stew demands a good stock.
I may be wrong in thinking the stew was made with water; they could have used a very weak stock. Either way the meat and vegetables in the stew had precious little flavor; it was served over white rice, which would ideally have soaked up lots of lamb flavor from the stew -- in the event, the stew had no flavor to spare and the rice tasted like cardboard.
On the plus side, they served a very nice roll with the stew. I think it came from Sullivan Street Bakery. Also it was nice to sit out in the sun, on the bench in front of the cafe next door to the kiosk, and eat my lunch. Maybe I'll go back and try their split-pea soup (which is less demanding to make as far as stock); but at the prices they are charging probably not.
