On the A store (to the map above) and go a block south, on the east side (beside a Chinese church), there is a new Chinese Super Market just opened not long ago, it is a direct competitor to T&T. I was there a few weeks ago, its prices are very competitive to T&T, although the bakery selections are not as much.
According to my friends who went to the church, they are doing better business these days than T&T, and on the weekends, it is usually packed.
