First Dates Ireland, The Supervet and Death in Paradise are just three of tonight's many returning shows . . .
Pick of the Day
First Dates Ireland, 9.30pm, RTÉ 2
Always a popular show - perhaps because it's got a more benign approach than its UK counterpart - First Dates Maitre D' Mateo opens the doors of the restaurant to welcome a new selection of singletons.
First up are double daters Mary and Martina from Limerick, twins who do not share the same taste in men. Will clean-cut Sulvester and dashing stonemason David be what they're looking for?
Meanwhile, animation student Eric is worried that his stammer might ruin his date, while unrepentant ladies' man Barry-John from south Dublin meets his match in feisty model Katarina from Laois.
