The sign says Fiouna Catering and Take Out. It's on California St, right next to Bridge St. I haven't seen anything about it on C-hound yet.
I stopped by on my way home from work the other day. There's no place to sit inside, just a counter with some refrigerated stuff.
They weren't all that friendly or helpful, but I lunged into a choice. I got a large Zereshk Polo ($10.99) and a small Shirazi salad ($3.49).
Zereshk Polo was a chicken kebob (5 pieces) on top of a lot of really tasty and delicate saffron basmati rice with sweet & sour red currents.
The salad was a mix of cukes, tomato, onion, dried mint and lemon. It wasn't too big and there was a lot of liquid in it, so I tossed it with some lettuce, salt and more oil at home to stretch it out a bit.
It was all pretty good and I'd go back to try more stuff. It was enough for 2 medium appetites.
Now that I have a menu, I'd call ahead first, since it took about 15-20mins for it to be done and there's nothing to do while you wait except go into the spa next door and peruse the junk food and lottery tickets.
The hours are Mon-Sat 11am-8pm, Sun 11-6. Looks like their web page: www.fiouna.com has a pdf menu that looks the same as the one I got there.
