On occasion I'm asked which restaurants in Oxford I think are good places to take young families, but as someone with no children in my life I'm never sure what to say. So when I walked into Mamma Mia in Jericho one Friday night and saw several tables of families indulging in an end-of-the-week treat I thought I finally had an answer: surely a friendly Italian restaurant would be an ideal place to go with the bambini? But although the youngsters and their parents seemed to be enjoying themselves, I was disappointed.
