We came to Hapa Umi because of a groupon type deal, and felt very lucky that we had found this gem. It's quite a large space, tucked into the side of the Tourism Vancouver/Tickets Tonight building. Don't give up on looking for the door - it's worth it!
Our deal gave us a three course dinner which unfortunately meant that we missed out on sushi - it looked great as it went past the table. I started with the Fanny Bay tempura oysters, nicely presented in manageable pieces with a miso vinaigrette and pickled shallots. My dining partner's beef medallion things looked pretty great, and I don't even eat much meat. Our mains were some form of deliciously tender chicken for him, and salmon for me with gnocci, vegetables, sauce. All nicely presented, great sides, delicate flavours.
We were already quite satisfied, and then came dessert. Truly, one of THE BEST desserts I've ever had the pleasure to experience. The menu undersold it as a warm chocolate cake with banana tempura and vanilla ice cream. It was actually a good sized molten lava cake, with two generous pieces of warm banana tempura on the side. The textures and tastes complemented each other in a fabulous way. The cake was topped with fresh sliced strawberries and some carmelized sugar art. There were fresh blueberries, raspberries, and blackberries, and the ice cream was very tasty. Pretty much a party on my plate.
The only negative was that they all knew we were in a rush, but the service was on the slow side. Otherwise, my highest recommendation on this place.
PS - washrooms are lovely - three small self-contained rooms for each gender!
