Leo Fu's is a Calgary standard, or so I'm told. My beloved's family has been coming here for 30 odd years, and has never been disappointed. The food leans toward Canadianized old-school "dinner-for-4" style cooking - and that's fine by me. If that's what they've always done, they've certainly gotten good at it. Authenticity is such a fleeting thing anyway. Who's to say that a few decades of tradition isn't "authentic" by now?
To cut to the chase - I like it. The ginger beef, a Calgary specialty, is as good as I've had anywhere. The decor is old school too, like every slightly-upscale "Chinese" restaurant looked like a few decades ago - but very clean and well-preserved, having received a fresh coat of paint regularly. I'm not saying it's going to impress a date, but it's a comfortable place to sit.
To sum up - "traditional" Canadian/Chinese food, done very well, at reasonable prices. It's not a gourmet experience - it's just good comfort food. What's not to love about that?
