I work in this office building and have eaten here many times over the last 2 years. It's fine, as far as the food goes. It's reasonably good and affordably priced. However, as of this week, they have been closed down by AHS for "extreme unsanitary conditions". I won't be going back. For reference to food inspections here, simply google "ahs restaurant izumi calgary".
Edit: AHS has revised their original report, withdrawing their more inflammatory language. I have e-mailed to find out the reason for this retroactive edit.
Update: I had meant to update with the information from AHS, and then promptly forgot since I'm getting old or something. AHS advised that the original report was not withdrawn. It's just that only a certain number of current reports are available online. All of their original findings stood at the time it was then inspected. We still don't go there.
