Apart from the Camden Town market, other markets that can be visited in London are Covent Garden, Portobello and the market under the London Bridge, also called Borough Market.
The latter has a special charm. It is the oldest market in London and is dedicated to gastronomy where you will find all kinds of edible products. They open on Fridays and Saturdays and it is located in the southern part of the London Bridge. There is a great cultural variety in the cuisine that is offered, from hams, cheeses, exotic fruits and one leaves there with a fierce hunger. However, people come prepared and in exchange for a few pounds one takes off the craving by chopping some cheese, some olives, some good oysters, a fish and chips or some sandwiches.
Most of those who frequent the market are locals who come to look for specialties that are not found in regular stores.
Although it is not usual, if you want to eat sitting and calmly I recommend a pub called Wheatsheaf. It is located in front of the flower shops and they offer a succulent and generous roastbeef for less than 10 euros. It is not authentic on a market day but we were busted and needed to rest our legs for a while. Truly, we were fortunate and it is a place worth recommending.
It is also an ideal visit to complement with a walk to the Thames with the possibility of visiting The Globe - the theater that saw the first interpretations of Shakespeare's play - and also the National Gallery that by the way, you can access a free Good part of its plants.
The market is connected by subway with its own stop -London Bridge- and is joined by the Northern and Jubilee lines.
