It has been quite a few years since I have been to London and taken advantage of the restaurant scene. Needless to say, it has changed for the better and I am quite excited to dine at several of the recommendations made here on Chowhound, e.g., Langham for afternoon tea, Bombay Brasserie, Moro, etc..
I am, however, disappointed in one aspect of London dining; that is the practice of many restaurants reserving a table for only a certain period of time. I could, for example, book a table for 1930 but we would have to vacate by 2100. On a Saturday night, I prefer to go out for dinner and enjoy the eveing at the restaurant as you do on the Continent. This time-limit table policy reminds me of the turning tables practice of the States.
As a result, there was at least two restaurants we will not enjoy on our trip. That being said, London looks like a great place for a meal.
