The Hill is Home has an excellent write-up of our favorite cheeserie:

Bowers Cheese Shop has been catering to cheese freaks on Capitol Hill for 45 years. They run a tidy and efficient operation near the southern end of the Market. They are one of the few vendors who accept only cash, so plan accordingly. They are always extremely generous with their samples: in fact, one could spend dangerous amounts of time just standing around and basking in the niceness of Tessa or any of the other people who work the counter; eat one’s weight in bits of cheese; and develop a huge crush on that enormous saw-like cheese knife that cuts even the toughest aged cheese with ease.

We visit them at least once a week. At least. Their humbolt fog is amazing, and their selection of Virginian cheeses is stunning (and tasty)
