For where it is ... the shop was ok.
You could get bread (frozen), milk, softdrinks, meat packs (sausages, chops, mince), flour, noodles and various canned food (eg. spam, spaghetti). I ran low on meat by day six of my trip and bought some chops and sausages for $10.
I also shouted myself hot chips and a coke a couple of times ... very yummy after hard digging.
