Since I live 50 miles west of Hwy 6, this place (about 1 mile west of Hwy 6 on Westheimer) was a favorite. So far as I know it was the westernmost authentic Chinese/Vietnamese market in Houston (and therefore the closest one for me).
They did live crab & crawfish which were good to be able to get and reasonably cheap. Also canned staples for oriental food.
I was sorry to drive by last week and see it has closed down. The 99 Ranch in Sugar Land is probably now the closest for me. .
