First of all the food is truly delicious. Try the seafood chow mein...crispy and alternately saucy with large fresh shrimp and vegetables. Both types of crab dishes--the one with sauce and the dry one are very good though of course the former is more messy. They provide a small container of lemon water to rinse your fingers after you have demolished the crab.
All the different dishes we tried, including peking duck, fish and chicken dishes are all authentic. Though sweet and sour pork (boneless with pineapple) may seem a cliche for Chinese food, I think Ho Do's is the best from all the places we have gone to in Vancouver, Richmond, Burnaby and Surrey.
For different numbers of people, you can order from two to ten dishes with different price range so having a big party is not a problem. Then there is free crab and lettuce wrap in proportion to the number of your guests. We have eaten here for over two years and even order large party trays for parties and the food is always fresh, delicious and consistent.
As to the ambiance, don't expect a made over restaurant where the owner sacrificed food and value to impress you with the surroundings. No, from the bathroom sink propped up on a rusty pole to the tubs of water on top of the ceiling tiles that the staff nonchalantly lowered (it was leaking) in front of everyone, to the handwritten signs all in Chinese, this is truly an Anthony Bourdain travel experiene.
