Dining options in Colchester, England
Sorry, can't help you there, but I cannot urge you strongly enough to get out and see the countryside on the weekends and use the Good Pub Guide to find great country pubs to eat in (it recommends the Stockwell Arms in Colchester). I have used the Good Pub Guide for nearly 15 years and it has never let me down. Please post on your eating experiences when you get back -- there is a terrible paucity of info outside London on this Board. Have fun!
