Right now from where I am in SE London, if you look pretty much due south, about 25-30 degrees above the horizon is Jupiter.
If you train a pair of binoculars on it you should be able to see at least four of its moons. I daresay if you have a tripod and less light polution than we have in the metropolis() then you might get an even better view. Either way, I recommend it.
Edit to say- with 10x binos it appears very clearly as a disc, rather than just a dot.
