Borough Market London

I have been to Borough market, and enjoyed it a lot -but I'm not quite sure what you mean by "was it worth it". If you're staying in the neighborhood (Southwark) or nearby, it's worth a stop. But I wouldn't necessarily travel out of your way for it. The food is expensive, but they have lots of gourmet cheeses, breads, meats, etc. Also lots of things I'd never seen before (and didn't care to try). We picked up a few things for a picnic lunch, but it definitely wasn't a money saver. Your local Sainsbury's or Tesco will have cheaper food, but if you want to try something new and interesting, check it out. It's only open Th-Sa. so plan accordingly.

I always enjoy Borough Market, but it is definitely now a foodie haunt rather than a source of cheap foodstuffs. The atmosphere is fun though. There's some more details here

Only about 5 minutes walk away is London's only surviving galleried coaching inn - The George. A reasonable place for lunch and even if you're not hungry worth walking down to have a look. Again more details here

Is it worth it? You should check it out and decide for yourself. This is where I go to find good quality, unique foods. Most times I show up right before lunch and pick up ready cooked items. Last December it was a wonderful wild boar sausage sandwich to die for! Most folks visiting London find it very inconvenient to go back to their B&B or apartment to cook a meal & end up eating near where they are sightseeing. Budget minded folks with more time than money will plan out their day around cooking their meals. My suggestion is do breakfast at your B&B, make lunch to take with you, and plan on eating dinner out on heavier sightseeing days.

I definitely thought it was "worth it." I happened upon the Borough Market while exploring the neighborhood with my husband and had a delightful time strolling among the vendors, snagging a few samples and splurging on a handful of beautiful chocolate truffles.

For what it's worth, we find that having breakfast at our B&B, then eating lunch out (pubs or restaurants are cheaper at mid-day than in the evening) and THEN in the evening have our sandwiches or whatnot from Sainsbury or Tesco. Also, there are places open at lunchtime that aren't even open later on in the day.
