Eating your meal with the Alhambra as a backdrop is very pleasant.
Here is a list:
Mirador de Aixa
Amazing views of the Alhambra.
Mirador de Moraymar
There are great views from the teraza and there is a special sort of look out tower which seats a few people. You would probably have to go there and book it to be certain of getting it.

Ruta de Azafran
You would have to get a window seat to get a good view.

Huerta de Juan Ranas
There is also a cafe bar on the roof, you don't have to have a full meal. There are also 2 other places just under Mirador de San Nicolas which I haven't been to. Just go up to the mirador an look over the wall and you can see a bit of what they are like.

This is the line of bars in Paseo de Los Tristes. Most of the tables have great views of the Alhambra.
