The Ox and Anchor is situated next to the Pop In at 8 Backgate, Pittenweem, where it sells restaurant quality hot food.
Its hot food menu includes smash burgers on brioche buns, potato hash with sea bass, prawn subs, triple cooked hand cut fries and loaded fries.
Now co-owners Sian Linton and Nicola Boyter, who launched the business, want to make the pitch permanent, and have applied to Fife Council for retrospective approval.
The trailer sits in the private parking area leased from the Pop In, taking up approximately two parking spaces leaving room for a further four or five vehicles.
It operates from Thursday to Sunday, but will add a Wednesday opening from June.
Councillors and officers will consider the application in due course.
