I absolutely love Brazillian churrascurias!!! My first experience at one was in downtown San Diego 10 years ago. I hardly ever eat at restaurants, but I will spend $$$ to eat at a churrascuria!
And there are 2 of them in the SF bay area! It's not all beef, though- Filet mignon, flank steak, bacon-wrapped chicken breast, xl prawns, ribs, garlic steak, parmesean crusted pork, and more (like 14-16 different grilled protein choices), all delivered straight to your table by some guy dressed up like a gaucho who cuts the meat off of a spit onto your plate!!!! Don't even get me started on the all you can eat salad bar. They had me as soon as I saw the HUGE wheel of Parmigiano Reggiano sitting split on the salad bar with a chisel for picking chunks of cheese!
If you are in the area go to Espetus Churrascuria. If you are not, find one within 100 miles of wherever you are and prepare for meat drunkenness!
