Baguette Express, a Larkin Street banh mi specialist overshadowed by Saigon Sandwiches--the Jan Brady to its Marcia, if you will--also has these massive summer rolls made with cold and crisp lettuce, vermicelli noodles, whole shrimp and roasted pork and with a generous cup of dip. They really are huge, but since the only size comparisons I could think of to make were unappetizing--baby's forearm; mastiff's turd; rat in sleeping bag--I put my finger in the picture to give you a sense of scale.
