We got the groop back together (J & spacegrrl, S & D, Sta Salsera, me and Sarah) and checked out taco night at Dos Perros. Good friends, good food, good beer... pretty much all you can ask of a night out. I had the shrimp, pork carnitas, and beef heart tacos. The shrimp was outstanding -- nice and light and fresh. The pork was also very good but it was blow-your-head off spicy. Or at least the last mouthful was. Maybe a chunk of chile ended up there but it really kicked me in the head. Thank Grom there was a big bowl of rice and a beer within easy reach. Beef heart was also really good. Texturally it was a lot like tongue (all muscle, no fat) but the flavor was more just like super-beefy beef with hints of blood. Not heavy and rich like blood sausage, though. Others at the table had good things to say about the barbacoa and the squash and the duck carnitas. Sides (the aforementioned rice as well as beans) can be ordered family style for the table. The chips & salsa were both wonderful and the guacamole was the best I've ever had that wasn't made right in front of me (the tableside guac at Bonito Michoacan in Vegas remains my gold standard). Anyway, good times indeed. I certainly want to go back and try more of the menu. The only thing I'd do differently is to go either a bit earlier or a bit later. They show a movie in the downstairs room at 7 and that's when we got there. I think there must have been a good-sized crowd and the staff seemed to be stressing a bit to keep up with a roomful of orders all hitting at the same time. But that's only a quibble. Everyone was super nice even when things got a bit shaggy around the edges.
