It sucks there have been a couple bad experiences at Cafe Orchid lately. I don't visit them very often but I do get delivery from them now and then and I think their quality has remained consistent.
A frustration I have with many Turkish restaurants, Cafe Orchid included, is that they include many non-Turkish dishes on their menu. This extends beyond the levantine classics like baba ghanoush, hummus, falafel, and tabuli. Cafe Orchid's kebabs are a mixed bag of generic continental meat preparations and pretty expensive for what they are. I've always felt it's entirely too easy to order a mediocre meal there. Also it burns me that the imam bayildi, a classic Turkish dish, is such a small portion for 7 dollars. It's a fine rendition but something I rarely order because of the price.
That being said, Cafe Orchid remains my favorite Turkish joint in town and it's where I take people when I'd like to introduce them to Turkish food without making it myself. Some favorites include the lentil fingers, the eggplant salad (which they are inexplicably calling mussaka now), the white bean salad, the ezme, the stuffed grape leaves, the feta wraps, the fried liver, the icli kofte (which they're calling kibbe), the pides, and the zucchini pancakes. I'd recommend ordering a range of the appetizers and then rounding the meal out with some combination of manti (preferably without the tomato sauce), adana kebab with bulgur rice, hunkar begendi, iskender (with tomato sauce), and uskudar. If everyone at the table orders an entree and you split a couple appetizers you'll be missing out on many of their best dishes and have a higher price tag as well.
I recently got a delivery order from them and I was able to feed four people a great variety of food for $20 a person with a little leftover.
