You haven't done the Castro till you've lollygagged on the sun-drenched patio at the Flore – everyone winds up here sooner or later. Weekdays present the best chance to meet neighborhood regulars, who colonize the tables outside. Weekends get packed. Great happy-hour drink specials, like two-for-one margaritas. The food's good, too. Wi-fi weekdays only; no electrical outlets.
