I ought to remember the Dublin Castle's hours but I think its more like 2.30 than 4. The landlord, 'arry Conlon, is a real throwback to the old days. Its HIS pub and HE'S in charge. Nice bloke mind you.

Camden couldn't be easier from Bloomsbury, its about 3 or 4 stops on the Northern line. Thats the black one. You could even walk it though you wouldn't want to get lost in the estates on the way.

One tip though: don't stand within 50 yds of Camden tube looking gormlessly at an A-Z. Its nothing to be worried about but Camden has a vibrant "night time economy" if you catch my drift.
