Hiya Jingle - Pok Fu Lam Rd, like many others, is long.
It runs from the tip of Bonham (HKU's East Gate) all the way past the West Gate, and on the other side, past student halls, Belcher's, sport fields, etc.
Whereabouts on PFL, are you looking to live?
Guess I was mainly talking 'bout the slopes down from the pedestrian flyover leading straight from Haking Wong Building (West Gate).
The residential clusters there are modest, OLD buildings with quiet rest/sitting-out green bits - downhill paths, cut off from the roar of traffic. And if you're stroll closer to areas off Third St, Queen's Rd West, near Whitty St, little eateries are more in sight, catering for studenty, academic or office folk - and closing up relatively early: 8-ish, when everyone's off home. If you're nearer to Shek Tong Tsui, thus 10-12mins brisk walk from the KT tramline, there's more food choices, open for longer (albeit, very local).
Groceries, etc: don't suppose you're the wet-market frequenting type ... so the small Wellcome store near Whitty St (if I recall correctly) on the tramline road, would be handy, and opens till 10.30pm. But since you work smack bang in cosmo Central, the other shinier stores 'round there would definitely stock the varied, "international" stuff (when you've an occasional craving for it).
Hope this helps, in some wee way... Wouldn't want a newbie in our lil' town malnourished in any way
