Your uncle will be staying really close to Robson Street. It has nice boutiques, sidewalk cafes, gelato places, and lots of restaurants. For a good martini, margarita and large servings in a casual place, try Milestones restaurant on Robson. For something more intimate, try the restaurant in Stanley Park near the tennis courts (it used to be called the Beachhouse restaurant). He also has an extremely decadent chocolate dessert place directly across the street from his hotel. The chinese restaurant in the mall underneath the Hyatt is very good. The Hyatt is about 4 blocks away from the Sutton hotel.

Don't forget to visit the Granville island public market (my fav place). The french bakery there is heavenly!! Also, take a walk through Chinatown. Unfortunately, the best chinese restaurants are no longer in chinatown but it's a nice place to sightsee.

Taking the ferry to Victoria (the capital of British Columbia) is romantic. Beware, the summer crowds can cause long waits for the ferries. Victoria looks like a small English town. Make sure to have high tea at the Empress hotel.

Just a sliver of all that Vancouver has to offer.
