Avoid at all costs!
AVOID AT ALL COSTS! Just had my work Xmas drinks there and had an awful experience from start to end. Tried to reserve an area a few days and go and was told 'we don't take bookings in the Xmas period'. By then I should have known and picked another place but no...decided to give it a go anyway. We arrived early and picked a quiet area next to one of the bars, asked whether they were going to be serving drinks from that bar and got told 'maybe, we'll see'. During the course of the evening the bar staff was either rude or incompetent and sometime both...we got served several gin and tonics without ice and one time without tonic...by 7pm the place was pretty packed and we decided to leave. At that time I discovered that my brand new £300 karen millen coat had disappeared. Apart from one lady who took my number in case the coat turns up, the staff couldn't care less...
The Porterhouse is a typical tourist trap in a very touristy area, where they get away with bad service and with a shady clientele who sits there waiting for valuables to be left unattended.
