I met my son at Johnny's Beef last Sunday night. When I went to get my Beef, the line was too long, so I wandered across the street to order a Carne Asada Torta from Senor Jefe (a restaurant I had been meaning to check out anyway), which is owned by the owner of Spizzico. I've had Tortas all over the city, and I would give this a solid 9 on a scale of 10. Absolutely delicious! It certainly blows away anything available in (or near) Oak Park. Try it; you'll like it!
