Pretty much WYSIWYG here, and that's a good thing. Don't go with expectations of a high-end dining experience.
CMR is just a few minutes' walk from Istiklal street. I checked but didn't see a building number. As another reviewer said just look for the green sign - you can't miss it.
The "dürüm"- a standard serving - is a wrap with the main ingredient, pomegranate concentrate/syrup, lettuce, cilantro, and a bit of spicy sauce if you like (I definitely like). Actually, it's delicious & pretty much nails "umami." There's nothing else I've had like this so there's no way to make a comparison. It's healthy, light, simple, and at 3TL really you can't beat it if you're on the go.
