Muddy Waters Coffee House in San Francisco has quick and friendly service. The staff are really kind - the woman behind the counter even gave us a slice of cake when we came up just short of having enough cash to pay for it. The place has a friendly vibe, with the owner chatting comfortably with customers -- it's hard to tell who's a regular and who's a first timer, because everyone is treated like family.
The coffee cake is definitely a highlight. It's moist, has the right amount of sweetness, and is well-spiced, making it a tasty treat. However, the coffee itself falls short, tasting murky and bitter, which is naturally disappointing for a cafe.
Muddy Waters is also reasonably priced, especially considering the location. An important point to note for potential visitors is that the business operates on a cash-only basis, which can be an inconvenience, but as mentioned above, the staff are very understanding about this and probably wouldn't mind a quick ATM run.
Overall, while the coffee quality is lacking, the friendly service and delicious cake make Muddy Waters a decent choice. I can definitely see myself coming back here to work for a couple hours and support small businesses, and I suspect that I may have just gotten unlucky with my cup of joe. Try it out, see if it's for you.
