Are there interesting things to do in Ipswich on a Sunday day trip up from London? I like architecture, walking around a historic or natural area, going for tea, etc. Would it be better to suggest somewhere else to meet a friend who will be in Ipswich for the weekend? I'll need to get there by train/bus, though once I meet my friend, he will probably have access to a car. I'll be on vacation from N. America, and will only have a few days in London, so I do want to make the most of it if I leave London for the day.
