Pho Train is famous.
Seriously, my friends from Waterloo have seen videos of the historic Asian fight/faceplate that took place here. (Oh, btw, I don't know anyone who calls this place "Xe Lua". It's Pho Train.)
My review might be a bit skewed, seeing as how 90% of the time I eat here it is after consuming a substantial amount of alcohol. But in my experience, the pho here never disappoints at 3am on a Friday/Saturday night, when all the post-clubbing Asians (and some non-Asians who've caught on) gather for the age-old hangover cure. The avocado smoothie is also pretty dece, as are a few of their other drinks (the 3-colour-drink with jelly, red bean, and coconut milk is really good). The curry chicken I once sampled from here was also quite tasty.
I'll be back, with admittedly thinly veiled hopes of witnessing more drunken Asian drama.
