To be honest, I'm always surprised when I pass Pho Hung and find it overflowing with more patrons than all other Pho restaurants in the vicinity combined. I found both their pho and bun offerings to be perfectly serviceable but not noticeably better than any other Vietnamese restaurant along Spadina (and certainly not worth the extra premium you pay). For the same price you can get fancier dining at Pho 88. For more adventurous and authentic fare e.g. blood sausages, pop over to Xe Lua.
