I have many friends in London area. One of them particularly told me she is very fond of eating out at nice London restaurants.
She browses on Trustedplaces.com whenever she feels adventurous for new eat-out places. She knows the exact location of the restaurant she's going to visit and sometimes she can even view the menu before arriving at the restaurant.
She has invited me over to join her eat-out adventure but I had to decline for now as travelling with a toddler for long-haul flight is not really fun. Not now, but may be in the future when my boy is a little older and then I can travel with ease.
