Yes there is but we've not eaten there since Easter and it changes reglarly so will probably be different however there will probably be 3 choices for each course - it is a 3 course meal
We ate there on Christmas Day but ordered from normal menu. DD had vegetable sticks and dip (thousand island type dip) as starter, roast chicken breast, vegetables and potatoes (cant remember how cooked), dessert was a chocolate pudding & icecream type of pudding. There wasn't an alternative starter but from what I remember there were other alternatives for main course and dessert.
