As you may have guess...i'm picky boy and especially about food then i don't often go to eat "com sinh vien", student's rice. Last week, a bit crazy i accepted to go with some colleagues there, actually for a "bun cha" (a 'soup' with grilled pork and 'bun' noodles).
An appetizing bun cha: noodle, pork 'soup' & 'salad'
Despite a cockroach welcomed us, it was really good and really cheap (1$, but quite small) and i even didn't get sick after that!
Often my housemate told me it's safer to eat in the street or buy at markets than going to some supposedly good restaurants. I might tend to try it more often but it's not that easy. Most of the street restaurant have only one dish and... i dislike most of the dishes ><>
After the meal, we went to "ca fe" as usual. I was facing the inside while my colleagues were having some greedy stares at some foreigner girls outside. For some reason they said "2000" or "1000" and i asked why. The answer is : "in Vietnam you can buy handful of Xoi (sticky rice) of different size... '1000' is small while '5000' is the biggest one" and they added " but you have to take care of the importance of the sheets"... 99% of the time, young vietnamese girls give "some" help to their breast.
Finally, we went for some serious foot massage... altogether in a room so no possibility of bonus ;). It was a really nice and cheap place; the masseuses were laughing all the time with my colleagues (50% of the time was about me...).
Conclusion: even though you are very picky and relunctant like me you have to trust your local colleagues/friends to try new (possibly disgusting) things!
