The Princess Louise, was a Victorian Gin Palace, with mirror and tiles galore, segregated seating and extraordinary urinals. With pints of beer just over £2 you're laughing. It gets packed so we come for a lunchtime pint.
Old townhouse style building set in front of juxtaposing high risers makes for an odd placement, but internally it's a quirky spectacle. One half is dedicated to the sale of antiques - anything from old door handles to hallways lined with hunting trophies. The other half is a relaxed bar and hidden gourmet dining area constructed of similar furnishings [all for sale too]. Even if you don't wish to spend £'s, a walk around the place is advised.
This is the most genuine and unpretentious pub I have visited in London. The Palm Tree is on the east London canal outside of Victoria Park. You won't find it unless you know it's there. (And now you know!)
