I go to Simply Delicious about three times a month. The menu is very good value and very varied - sushi, Pho, robata, french fries, whatever you want.
The bento boxes are an excellent deal and you get lots of choices to make your own combos. There are lots of little dishes so it's fun to order a lot and share as a group. The sushi is always fresh and the rice prepared correctly.
Yes, the service is erratic. I'm convinced that the owner only hires extremely new Canadians who have never worked in a restaurant before - so don't be so hard on them. I tip decently and have tried to make a connection with a few of the wait staff so I will often get attention before someone else. Being a regular pays off sometimes.
It was an Argentinian steak house a very long time ago and the decor still reflects it. But the booths are big and comfy, the menu selection wide and the beer is cheap!
They did just raise their prices a little but it's still cheap. It used to be that my sister, my niece and myself would have our fill of sushi, sunomono, and tempura plus three beers and a diet coke for $24 but now it's a whopping $27. Where else in Vancouver can you eat a huge meal with a little bit of booze for $27?
