Freeb!rds is the only 24 hour resturant of the college student populated town of Isla Vista. Many college students bring their drunken or stoned heads to Freeb!rds at the wee hours of the morning and night, especially during the weekends where Isla Vista is known for their parties.
The portion servings in Freeb!rds are huge and you do get what you pay for, though it is still edging toward the pricey side for a burrito, if you get the works (sour cream and guacamole). With that being said, Freeb!rds has a cult following, but is highly overrated. Yes the burritos are good but they are not the "best in the world" or even of Isla Vista.
Freeb!rds is only worth a try if you are a tourist in UCSB, an oreintation kid, or you have the munchies at strange times in the night. Otherwise there are much better dinning services in the area.
