There is a beach shack at the end of the beach......but I think it is mainly geared at the locals. Lots of fishing boats pulled up down there. Lots of garbage and dirty water also, so not very pretty. I just viewed it from the water so not sure if just a bar or also food.
Outside the property there is a main road with a bunch of shops and food places, again all geared towards locals.

Best bet for food is head to town, but taxi costs negate the savings. You can get the shuttle also, but limited seats on shuttle so would not be fair to hog seats every night just to go to restaurant.
There are a couple of places before town that are also good, we ate at Nemo and CAMI (see tripadvisor) and both were very nice. Also went to Crab House in town and while expensive for Vietnam, would still consider it good value.
