This is a busy restaurant on Spadina just outside of Kensington. My friend and I visit Pho Hung from time to time when craving some Vietnamese cuisine. There are a couple of dishes we always rotate ... fried frog legs.... rare beef with lemon juice (this is spicy!! we usually avoid the tiny pieces of chillies) .... and other staples such as a bun/vermicelli or a rice dish. I'm not thrilled with the pho here so I'll go elsewhere when I want some pho.
Service is simple and efficient. You should order everything you want all at once as it may prove difficult to flag down servers after initial contact. Turnover is quick, so even if there's a big queue for tables, it will pass quickly. This is not a place to linger at leisure.
I always have to remember to bring cash with me as they don't accept any other types of payments. This is slightly annoying as I generally use credit/debit everywhere.
