The live music at La Fabrica usually doesn’t get going until about 9pm on most nights. And that’s about when you should try to get here, because while the small plates and ceviche-heavy menu is just OK, when it’s combined with some fruity cocktails, Brazilian jazz, and the occasional Big Papi sighting (so we hear), then this place is probably more fun than any other place in Central Square (or at least, more fun than your apartment). If you want to go nuts, order one of the rice dishes that’s doused in rum and lit on fire, because you can’t tell us you’ve never been tempted to douse something in rum in light it on fire.
