Despite the expensive products, and the lack of breakfast- the stands and restaurants only open up later, most of the experience is roaming about, walking through the stalls and looking around. Many of the stands offer a taste of their merchandise.
If you happen to be in the market past noon, you can wait for the market to switch over to trendy bars. These fill up quickly with the Londoners who come for an afternoon beer.
For those not interested on spending money- if you arrive an hour before closing time, you will find that many stalls sell their goods at half price. You can buy pastries, bread, cakes, cookies, soups and cooked foods.
The Borough Market underwent serious renovations before becoming what it is now: a market for good quality gourmet food, with prices to match. The market began to function as a social and cultural center, offering many culinary activities. The best chefs of Britain and Europe frequent the market, venturing to see and be seen.
