Dual menus is the battle we Gweilos who want to taste "authentic" "Chinese" food must endure. I sometimes order "blind" from the group dinners described in the menu only in Chinese just to try new things.
Do you know restaurants where this is not a problem? Here are some of my choices:
We usually go to the Saiwoo Gardens, known to its regulars simply as the Saiwoo ( accross from the Pagolac) which is a popular Cantonese place open for dinner only until the wee hours. They have an extensive English menu which includes what we think are "authentic" dishes because we have seen them in other tables being eaten by obviously Oriental families ( the first two pages have "western chinese dishes" like chicken balls in day-glo sauce for patrons that are looking for that type of food). And sometimes we order off the menu ( e.g. seasonal vegetables) So we think we know enough to get mostly authentic food (also having eaten Chinese in Vancouver and Richmond).
I have also have heard good things about the Old Szechuan on 107 Ave and 102 Street in terms of regional authenticity.
Then there is the Happy Garden,6525 111 Street, one of the pioneers of "Mongolian " and Northern Chinese food in Edmonton, whose grungy decor needed renovation already 35 years ago when it first opened. It still has devotees for classics such a Mu Shoo pork, green onion cakes, Szechuan beef etc.
There is also authentic Shanghai style food at Shanghai 456, Building 18, 49 Airport Road, , a family run restaurant that serves also the flying club at the Municipal airport with western popular dishes and sandwiches
Lastly, there are places where they serve simple fare and do not discriminate if you order something from the menu, such as Delicious Delicious on Stony Plain and 155 Street ,or the Hong Kong Bakery, or BBQ King on 97th street (BBQ meats on rice)
