Chez Xuan

Right across from that great little climbing gym - VietClimb - is Chez Xuan (no website, just reviews on New Hanoian).  It's a great place to get a good bit of Australian beef, a tasty mojito, and a big bowl of fries.  This place has outdoor seating, a great little garden, and pentanque.  It's not on any sort of main drag, so the loudest thing you really hear are the guys playing soccer on the fields in the lot next door.
