If you look up unassuming in the dictionary you might find a photo of Mekong. Like many Vietnamese restaurants the interior is austere and utilitarian, but it's clean and homey. The first time I had lunch there I wasn't expecting much, I kind of had "the usual" the vermicelli with spring rolls and bbq pork. To my surprise it was really, really good and really, really fresh.
The appetizer was what really floored me though, the spicy beef on lalot leaves. I don't know exactly what a lalot tree is, but take it from me those who like this appetizer, like it "lalot."
Since then I've become a regular, any time I'm in the neighbourhood. I feel almost guilty eating here because the food is so ridiculously cheap and good. They should charge more. I should also mention that the service is also excellent and very friendly.
Try this place and thank me!
