The second photo needs the translation. The inscription made by a stencil is advertising of grocery goods. I think this is a wholesale warehouse. "Соль, греча, кофе, мясо" — "Salt, buckwheat, coffee, meat". Text written by hand — "Юрк! Тоска". Юрк is a short form of the name Yuri, тоска — melancholy, ennui.
