I'd like to note that Kirin Seafood (Cambie) has better geoduck congee than Sun Sui Wah (Richmond).
At Kirin, it was probably $14.95 Canadian (approx US$11) for a large serving that was sufficient for 6 small ceramic bowls. The serving size at SSW was about the same, at a lower price of $9.95 (promotional). Both are good prices, although admittedly geoduck is relatively inexpensive in this city.
However, Kirin's geoduck congee had less coarse rice incorporated. Also, SSW had significant amounts of MSG that made the flavor of the congee more artificial. Third, Kirin's came with a set of possible condiments (which I did not use) -- spring onions, roasted peanuts, etc. Finally, Kirin's had more of the "white" fleshy, higher quality parts of the geoduck, and arguably slightly more geoduck.
Therefore, Kirin Cambie's beats SSW Richmond hands-down on geoduck congee. The former has fairly good congee; the latter, average-minus.
