We were on a high after seeing the Brownlee's make Olympic history in the Hyde Park Triathlon. Initially lured in by the three course special for about £10.50, the Pizza Pasta Bar seemed like the ideal venue. Our children are 6 and 8 and clearly do not need or want adult sized portions, yet despite having the conversation about children's size portions they ended up with adult portions.....most of which ended up uneaten and wasted on their plates. When the bill came we ended up having to pay the full adult price, which didn't make us happy. Restaurants need to be flexible and cater for the customer's needs. Three of us went for tiramisu; two were fine but mine was clearly from a new batch that had only just been made. The base was tough and chewy and still very warm, with a layer of creamy stuff slapped on top. One of the worst puddings I have ever had. The service was OK but we will not be going back. A disappointing end to a fantastic day.Andrew, Janet, Leo and Imogen.
