A recent visit to Shoom Shoom confirmed my previous experience with Iranian restaurants. Absolutely bland and tasteless food. The concept of seasoning seems completely foreign to them. The concept of condiment is also foreign, so there was no way to doctor the food. The only exception was the sweet potato fries, which were executed well. There are a few other minor problems, the bread served with the meal was far from fresh and the menu, especially the selection of appetizers, was extremely limited.
It's really a shame because the service is excellent and they try very hard. But they might as well put cardboard on their menu, you'd never be able to tell the difference from their other dishes.
