Okay, I know what you've all been waiting for: Mark's report on the Creamy Tomato Soup at Souplantation. I had a disappointing bowl of the stuff last Monday but vowed to try, try again. On Thursday, I lunched there with my pals Vince Waldron and Dan Castellaneta and the soup was much better. Then last evening, Carolyn and I went there for dinner and it was terrific. So I'm writing Monday's soup off as an aberration…and will be back many times before March is over.
