A note of explanation: I've been in Malaga for a long weekend with my girlfriend with the intention to eat at the four vegan/vegetarian places of the city. Unfortunately one was closed, therefore we managed to eat at (in order of preference): Cañadú, El Piano (but it was "almost closed", see below), and El vegetariano del Alcazabilla.
On Friday August 14th we went to El Piano and found it basically closed (a sign on the table was saying "On holidays from August 14th to August 23rd"...). The owner was in, though, and we managed to buy some tapas. I had 4 tapas for 5.95 EUR, and my girlfriend had 2 tapas for 3.95 EUR. We also bought two chocolate brownies (2.50 EUR each). So one thing is clear: everything is very cheap!
The tapas were good, but it was strange to see that there was nothing prepared with chick peas/beans/seitan/tofu... basically it was vegetables all around. Nothing wrong with that, but we would have appreciated something more "substantial". Also, maybe the lack of choice was simply due to the place being essentially closed for holidays!
Brownies were good, but a bit dry.

Cons: Food tastes good but not amazing
