Kasbah - great food (try the Moroccan Cigars) and decent prices, but lousy service, always showing lubavitcher rebbe videos and always incredibly crowded. Maybe a 3.5 for the ambience but a 4.5 for food and prices (prices being Manhattan kosher prices).
Nargilah - Decent food, nothing special, average prices. Maybe a 3.
Colbeh - Lousy food (though my wife loves it) and very overpriced. Maybe a 1. I admit I may be a bit biased against Colbeh (though I always disliked their food) as the one in Manhattan canceled our Shevah Brochus one day before the sheva brochus because they got a "better offer." -
Do you mean Darna instead of Kasbah? Darna is Moroccan, while Kasbah is really more deli than anything else. I've only been to Colbeh once or twice and never paid so I can't comment on the price, but I enjoyed the food. Nargila is average food and average price. I enjoy Darna although it's probably a touch more expensive than Nargila.
