There aren’t many downtown Persian restaurants, so on weekends, expect the long lines at Takht-e Tavoos to spill into the Little Portugal neighborhood. It’ll be worth the wait: after dining at Tavoos, author and former dining critic Ruth Reichlwrote that she left floating. (Tables for a late breakfast or lunch are easier to come by during the week.) Thanks to dishes like kaleh pacheh, a classic Iranian breakfast of a sheep’s tongue and a hoof, the sweet-meets-savoryguisavah, a dish of eggs cooked with dates and walnuts, and warm house flatbread to sop it up, you will leave floating too.
