We did go to one place that had this really good pea mash side, but the fish & chips was pretty average at best. Other places basically gave us a cup of unseasoned peas (someone ordered teh Fish & Chips at almost every meal, and I tried most). I couldn't get my family away from the "touristy" areas though for the most part. They have... particular tastes (the whole impetus for the trip was a bit controvversial). I honestly don't doubt that there is some good food to be had in London, but I sure didn't find it.
