New York has Katz’s. L.A. has Langer’s. The Bay Area, on the other hand, has never really had a true destination pastrami spot – at least not until Delirama opened its cheery Solano Avenue storefront in Berkeley two summers ago. Biting into the restaurant’s “OG” sandwich for the first time, I could imagine a future, 10 or 20 years from now, when Delirama would be exactly that: the kind of beloved neighborhood institution that out-of-towners would plan road trips around.
