Add the language you don't want to see to the preferred content languages in your browser settings and then make sure it's the last one in the list. Works with most Google services and many others to stop the automatic language selection based on IP.
It feels so weird because I rely on Google Translate a lot. All from the same company :)
EDIT: Just tried it. It still feels weird. I'm in italy right now, and Google leads me to "Google Italia", but then the UI is in English. Ah well, solves my problem I guess. Thanks man!
