We still go out about once a week to a garden centre for lunch and can’t say I’ve noticed any difference in the prices. Except all the kids at half term…
Let them eat Cake, if they can afford it. 
You’re very lucky then because even our little village bakery has had to put their prices up. Rolls, loaves, cakes, sausage rolls all gone up substantially.
Most places just guess at a price increase. One cafe near us is now charging over £7 for a toasted sandwich with a tiny scrap of lettuce and cucumber on the side. Last week we were in another town and a cafe was charging £3.15 just the same small dressing but far more cheese filling.
Thing is, they will never come down again. Prices never do.
