As both photographer & reviewer I do take & post photos of food, why not? It is part of many pubs and if the food looks nice and good value why not share the experience with a photo?
I also take, and post, pictures of the view if it is pleasant. such as
view across a harbour, or pleasant river running through the grounds for instance. Conversely I try & include cr@p surroundings / landscape if applicable, like huge oil tanks towering over the pub. And I take the car parks sometimes, may as well know if you can get in there or not
I also photo & post any notices outside or in that my be useful, like
history or background info of pub or notices
For me it is all about informing others who may not be [gasp] in awe of real ales and just want a pleasant pub they can go in without wondering what it will be like, and as pointed out, picture, kilo words etc
Like others I have photographed pubs [but not been in] in nearby city, in my case all of the pubs in Portsmouth / Southsea and surrounding areas, but just cannot keep up with constant name changes, new colour of outside etc
I have even photographed toilet doors with a nice mural on it
