Never mind the name: once you've sampled the carnitas (slow-roasted pork) tacos and passion-fruit-habañero margaritas, you'll be in no position to debate authenticity or grammar – or say anything besides 'uno mas, por favor' ('another, please'). Choose four tacos for $20, including seasonal vegetarian options. No reservations, but while you wait you can work through the 100-tequila menu at the bar.
Tacolicious' popularity has spawned sister restaurants in the Marina, North Beach, Palo Alto and San Jose.
