this bar advertises lunch for a fiver, and thats what you get - there are other choices, but i wouldn't go past this - not your usual £5 lunch, but actual decent food for the price they advertise.
I'm not from London, but am a regular visitor, and I will be here again - the staff we met were 100%, the whole place was clean and tidy and the food was worth a lot more than I paid - highly recommend it! :-)
The Pack Horse & Talbot is a traditional pub serving a good selection of beers and pub food.
