My DP booked a well-known restaurant for a special occasion back in February. At the time a set-price menu was available which he said he would have - he confirmed the booking by email but did not directly refer to this menu. We have now found out that the price of the set menu has dramatically increased effective the day we are due to go. We found this out by chance. The restaurant has refused to give us the original price. Effectively the cost will double, and as we are a fairly large party i feel this is grossly unfair. We don't want to cancel because some guests are coming a long way. Any advice welcome!
