Lunch on the run yesterday was a plain ol' hot dog from the What's Up Dog on Bush in SF's Financial District. Even though it was rather late in the lunch hour, the grilled dog served up instantly seemed in fresh and in good form without telltale dessication from holding too long. All beef, it had a snappy casing and nice spicing. The bun was a bit dry, not toasted, but good integrity. When I asked the source, the employee didn't know but volunteered that it was different than the usual bun in use and might become a replacement. I would vote for it.
