^^ Tony, Shinjuku is fine. I stayed at the Keio Plaza in west Shinjuku which was 200m from bars and restaurants or you can walk across to the east side of the station and go to bars there. Next time I will give Shibuya a go, it's only a couple of stops away on the same line so it's no less convenient and there are plenty of small and large places to shop and eat...there must be the worlds highest density of Macccas in Shibuya lol and there s Kripsy Creme as well mmmmm. You wouldn't be disappointed staying in either place. Just make sure you don't end up in a room next to a rail line.
