I'm a huge fan of Ike's. I've been twice now and have had great experiences (very friendly staff). Ike Shehadeh (whose cartoon face is plastered on every restaurant) opened his first restaurant ten years ago in San Francisco's Castro District after being nearly homeless. Ike's are known for their variety of sandwiches that are named after well-known celebrities. The use a bread that is popular in the Bay area called Dutch Crunch bread (or Tiger bread). The sandwiches are unique because of "Ike's Dirty Secret Sauce" - a creamy aioli that is baked into the bread and smeared onto the sandwiches. So far I have tried the Manage a Trois and the Meatless Mike (Vegan meatballs). The sandwiches are pretty large and the bread is very soft and moist. They have many vegetarian options and very order comes with a free caramel-green apple lollipop for dessert.
