It's worth a trip to Shiraz simply for the food, which is fantastic. A large choice of Persian dishes, with very well-balanced flavours, and in good quantity, too.
Then there's the host -- Ali, I think -- friendly and welcoming, and really knows his way around the tastes. Happy to recommend something, or explain the way to get the most out of the dish you've chosen ("try it without the lime first, but then crush the lime into the stew; it completely changes the texture...")
The prices are pretty keen for what you get, too -- it's not stunningly cheap, but my parents came away pleasantly surprised by last night's bill, finding it good value for money.
Well worth a trip, and fantastic if you happen to live in Hotwells; having this sort of restaurant within walking distance is a real benefit to the area. read more
