As San Francisco continues to get more and more gentrified and expensive, it's good to know places like this hole in the wall still exist. This place is basically a corner market that has a built in lunch counter. So you can buy some package beer, pull up a seat at the lunch counter for one of the massive (and cheap) tortas they cook up on site. The highlight? The greasy, decadent Cubana (Cuban pork roast sandwich).
Grabbed a decent dinner here with my friend who lives in Russian Hill, and I'd say it's fairly well done bar food. The sliders were tasty and the truffle fries (glorified french fries) were above average. The prices were a little high (If you're going to charge over $10 for a hamburger, it'd better get me full). The service wasn't the greatest, so I'd advice to stay away from this place during rush hours.
In the Gay Castro District -in front of the cinema-, Likewise is the perfect place to rest and to have some very good food in the best atmosphere.
Back in the day, you were lucky if you were served a drink here. That was before longtime owner Bruno Mooshei died in 2000. The old curmudgeon would often ask patrons to leave if he didn't like the way they looked or if they didn't order their drink quickly enough. These days things aren't so strict, but the bar has retained the Middle Eastern aesthetic that it had back when legendary Chronicle columnist Herb Caen frequented the joint, dubbing it the "the Holy Shrine of the Dry Martini."
If you're anything like me, whenever you put on some Stan Getz or Astrud Gilberto albums, you can't help but fantasize about being in some Brazilian chantey, sipping Caipirinha and dancing sultrily with someone of the opposite sex. This place doesn't quite capture the romanticized version of Brazil I have in my head, but it comes kinda close. And it's got great food. For some reason it hasn't really caught on yet, so it's never packed. Nor is it too expensive.
