What is it, exactly?

I walk by this market quite frequently and have finally found myself in front of it with a camera.

Is it Maxi, or Mini?  Is it a market with identity issues?  It's really quite confusing.

It is larger than most of the markets you find in the neighborhoods, but is it the maximum size a mini market can be before it must simply be called a market?  It's certainly nowhere near a "super" market.  

Perhaps the sign was a deal, so they opted for the cheap and easy route to market naming.  Regardless of how fluent I ever get in Greek, I probably won't be asking the owners for clarification.
