Sizzling Pubs review: service and food

We booked a table for 4 on a Sunday 29th December 2019. on arrival no one was there to show us to our reserved table. We had to ask at the bar, we were then seated where we decided to order Sunday lunch 3 for beef and 1 chicken. We ordered our food, which didn't turn up until 55 minutes after our order was placed.
On arrival food was Luke warm with a piece of what can only be described as braised steak not as stated in the menu, with honey glazed parsnips there wasn't even one on the plate, along with carrots which also had the top bits in, pease and green beans which had been cooked within an inch of their lives and a slither of cabbage along with 4 small frozen roast potatoes the mash was slopped on the plate and what we can presume was stuffing appeared to have a hard casing round. The food was tasteless bland and very poorly presented, it was cold and for the cost an absolute rip off and huge disappointment due to it being a family meal. We spoke to the manager who gave us a full refund along with 2 £5 vouchers which co incidentally run out on 31.01.2020. Along with puddings all round which were also not exactly warm. My parents have eaten here many times be gave always said how nice the food was but today I really don't know what hapoeved
