Yup the rent looks high but I dont know what the market rate is. There is a link through to the Late Knights Brewery on another thread where the guy involved talks about running pubs that serve food. About one in Bromley he says:

Rent and Rates at the Old Bank would need just over 800 quid of that before you had to cover other costs like staff, produce, power, etc...and then profit.

It is interesting to see some of the numbers involved - I'm sure I'm not the only person here who has had pipe dreams of setting up a shop in SE23 and not really being able to get my head round the likely costs and takings.
