Honestly, it depends on the day but living in malaga we have been maybe 4 times and the service is always poor and slow.
The food is not bad on the whole but it is expensive. After all 15euros for just the burger., this may be accepted if the service was better and the portions a little larger.
We did notice the last time we went the portions have shrunk, but the price has not followed suit.
It is annoying when there are 3 staff and 2 are chatting while u are looking to get served.
