Vancouver is beautiful and expensive.  There are at least 400 Nepalese in the area.  There are many nice areas.  There are many outdoor activities.  It depends on what you like..

Some of the activities/areas of interest include

-Whale watching

-Vancouver Acquarium

-Capilano Suspension Bridge

-Imax

-China Town

-Lookout at Harbror Center

-Stanley Park

-Gastown

-Dr SUn Yat Sen Chinese Garden

-Downtown

--There are nice beaches as well..

Food--

Many restuarants..

Vibrant city with lots of immigrants specially from China/Hongkong.

Public Transportation..

Saw many buses, but not sure how convinient the system is ...We rented a car in Seattle so didn't had to worry about that.  But I guess they are pretty good.

But if you know some one there then he/she should know about these places...

Enjoy!!!

If you have some time then I would suggest you to visit Victoria as well.  Ferry ride is not that bad.

Met a Nepali in Victoria also who ws running his own store.
