Kim Bo is the only pho within lunchtime walking distance of my office. If there were any other choices, I'd never go there. But sometimes, you just need pho, you know?
The interior is dark and cluttered. The service is quick-ish and the prices are cheap. I usually get the standard rare beef pho, and it is nothing remarkable. Last time, I ordered a spicy noodle soup (was it Hue style? I forget) and it looked and tasted like they had simply dumped a liberal amount of chili oil into the regular pho. The flavour was harsh.
Kim Bo is apparently a satisfactory choice for doctors and nurses on break from Toronto Western Hospital across the street. But who says medical professionals have great taste in restaurants? I expect their choices are also limited by a short lunch hour schedule.
