Clover has the following snacks, Burger, Pork Pies, Scotch Pies, Lasange, toasted sandwiches, chips and a few other things. After 2 hours of happy hour the 2 scotch pies I ate tasted great! and only 2.50 Euro each. However it is all microwaved food, ok for a snack, but probably not sufficient for your evening meal.
There is also quite an extensive desert menu, surprisingly enough
Aparantly the menu will get better once the restaurant next door opens.
