The pho was pretty underwhelming at Star King. While the portions were generous and meat quality was above average, the broth was very oily. It is probably the oiliest pho soup base I have ever had. It was also salty and surprisingly bland. Compared to other places in Toronto, I would definitely rank their pho in the bottom-tier. I do realize that pho is a pretty personal thing, so who knows, maybe you'll like it.
However, the calamari that we ordered was pretty crispy and tasty. I would not come back for the pho, but perhaps I would come back to try other items on the menu.
As others have mentioned, the location of the restaurant makes it hard to find parking at times. Unlike most Vietnamese restaurants, the physical space is large and the seating is very comfortable.
