Food review: all day Americana
Focus is very much on all-day dining at the recently spruced up Diner in Camden. Whether you're just getting started, or looking for a recovery from the night before, The Diner Breakfast Burger will sort you right out. The Freakshow Chicken with hot sauce will blow away a few cobwebs — and leave you craving more. As for the roof terrace; it's an ideal sun trap on those balmy summer days, whether you're on the milkshakes, or something a little harder (Bacon Mary, anyone?).
