Galaxy defenders

There is a building that I walk by on a semi regular basis. It's along a main road, amidst other perfectly normal buildings. There's some offices, a Pizza hut, stuff like that. Like a strip mall, all the buildings are connected but they all have individual fronts. 

The particular building in questions is all white brick and about twice the size as the rest. There are no windows. There is one door centered in the sea of white. It has a pretty intense handle and simply says ENTRANCE in royal blue letters.

Among all the other buildings, this one stands out. It's creepy and ominous. I've always wanted to go inside, half expecting it to look like the building from Men in Black. Who knows what kind of crazy shenanigans go on behind that mysterious door...

Today I found out that building is just a contact manufacturer. Such a let down.
