Hi jokeru,
I've more or less read the indications buzer ko has given to you (which are definately great) and I think I can add something else. There's an area called
El Tubo, at the end of "Paseo de la Indepedencia" street, in which there are a lot of bars and restaurants where you can taste loads of different food, just for you to know.
Have a good time here
