Check out WeWork on Townsend St. They've got solid WiFi and free fancy coffee, plus beer on tap if you're into that. It's a bit pricey but worth it imo.

Wifi isn't everything, but Narrow Street near Trader Joe's is a nice spot too. Less known, so it's usually pretty quiet and productive.

Bespoke is another solid choice. Located inside the Westfield Mall, they've got an amazing space with strong WiFi, free coffee, and snacks. Plus, the proximity to the mall means tons of lunch options.

Haven't tried many places but a friend said Covo is chill. Decent WiFi, comfortable workspaces, and coffee's good. Worth checking out.

Impact Hub is great, especially if you're into networking with other startups. Plus, lots of events that could be useful for networking.

Workshop Cafe on Mission St. is pretty cool. Pay by the minute spaces, which I find super flexible. Wifi's strong, coffee's good. Can get crowded tho.

All these places are probs gonna cost you a lot. Maybe try finding a good cafe instead? Trouble Coffee or Blue Bottle have decent vibes for working.

Galvanize on Howard Street is pretty dope. They've got a great community vibe, awesome coffee and snacks, and the WiFi is blazing fast.
