Decent selection of groceries, although prices tend to be a bit higher than other Asian supermarkets nearby. Their general environment is very clean and well kept; in particular, their fish market is one of the cleanest ones I've seen.
On weekends they have small booths for samples and Saturday mornings there are certain dimsum specials (although the prices are better at the T & T near Milliken).
The parking here is definitely a plus, with lots of spaces, especially because the other smaller stores don't get too much business. There's underground and above-ground parking which is very convenient in the rain/snow.
