I've not been to their Waterfront stand. I wouldn't pay too much attention to any signs with questionable English... that's surely not what they mean, as they speak very little to no actual English, and probably meant something completely different. It's strange their menu would be limited, though I think the Waterfront location was supposed to have more of their "specialty" items like the Ume dog. They have quite a lot of copycats around town now, too! I've seen two carts selling "Japanese style hotdogs" and at the Calgary Stampede this year there was one lol. You can always order a plain hot dog, even if it is not on the menu. Yeah, they'll probably giggle at you, but so is the risk
Like going to a seafood restaurant and ordering chicken. The Robson Store is always extremely busy, I almost feel bad for the people working there...! I have heard their pay is $12 - $15 / hour. You can make up your mind whether that's good enough or not.
Most of their employees definitely are pretty FOB Japanese
Though they have a white girl working at Robson St. That was strange.
BTW, I have a hunch "respect" was meant to be "enjoy", lost in translation. Depending on how you write it in Japanese and type it in to Google Translate~ lol
