I usually come here for when I'm in the area and starved for food, but over the weekend I actually went a little out of my way to get here, mostly because I didn't want to go home yet. It's their deli/bakery section off the registers and there is a multitude of selections to choose from hot, ready made dishes to pre-assembled cold items. The buns are good (we had the shredded dry pork and seaweed buns) with a soft, chewy texture, so soft in fact that it could probably outlive styrofoam. The Vietnamese sandwich was more akin to a basic submarine sandwich while using Vietnamese cold cuts and pickled veggies. The bread was certainly not fresh but overall a filling compromise. I've sampled many of the other items here before and more or less it's either hit or miss, many of which are overpriced factoring in quality.
Service is like any other chinese outfit - if you know someone working behind the counter, it's an advantage of sorts. Otherwise expect to be harried by other customers who claw and yell.
While entirely a supermarket setting, they actually have a small area of seating for dine in patrons, good enough for a mildly comfortable dining experience.
The convenience factor here is through the roof.
