As others have said, the Corner Store is an interesting convenience/curry combo shop.
It's easily overlooked/missed as it's got little more than an awning to distinguish it from the other buildings along Willy street. If you happen to find it, it does have delicious, reasonably priced curries.
I believe they've raised their prices since last time I was there, but it's now $7.25 for what I believe is a 1 pint container, packed to the brim.
Very friendly staff; I was genuinely thanked for stopping by.
In summary, a great little curry place (I can't attest to the rest of the menu), although their increased prices detract from the original charm for me; to my knowledge there's no longer a sub-$7 thai place around, except perhaps Rising Sons' lunch special.
