Covent Garden is a little hard to review, as it's not truly one location - it's a huge range of vendors all under one roof. Each vendor has their own unique qualities, and I haven't been to them all, so take this review for what it's worth.
Covent Garden Market is located in downtown London - perfect if you work downtown, but they also have plenty of free parking underground off king street (with validation) if you don't. It closes in late afternoon so it's great for some daytime shopping or lunch, but don't try to come in the evening.
The actual building itself is great. It's huge, and always clean. The bathrooms are always clean as well. There is lots of seating, though it can fill up if you're in for lunch. There is also seating outside, and on the second floor.
As for vendors, there is a huge variety. I usually come in for produce at one of the main produce vendors. They tend to carry lots of local options. Prices vary, some of it is super cheap, some of it is way more expensive than the grocery store - you just have to know your prices.
There are several butchers, as well as a cheese stand with a HUGE selection of cheeses from all over the world. Glenda's is another favourite stop, I always pick up hummus.
There are several spots to get ice cream or chocolates, and quite a few ready-made food options such as Chinese, Italian, soup, middle eastern, thai, Korean, Caribbean, Japanese that are great for lunch. Of the ones I've been to, I'd recommend any of them, except maybe the Chinese place. There are also a few I haven't gone to, so again, take it for what it's worth.
There is also a tea shop on the second floor, and lots of spots to get crafts or decor.
Overall, stop in and take a look, hopefully you'll find something you like!
