Work lunch at Pun Kum, 31 Windmill Street W1T 2JM. Two courses for £7.50 is undoubtedly excellent value, but my pad Thai wasn't very good. It was too sweet, with a discernible lack of any ingredients apart from noodles. Pun Kum is good for the price (not to mention a laugh at the suggestive name) but won't be high up on my lunchtime champions list.
