Hello, I am sorry for not replying sooner.
I think the lacquerware store you are talking about is Shikki no Asobe store.(漆器のアソベ). The store used to be facing Shijo street, but they have MOVED to Shijo Higashinotoin-sagaru, which is south from Shijo-street X Higashinotoin-street crossing.
They are still doing business, of course; it is a really popular shinise store, that has started in 1807.
