Instead, I pulled out my phone, jumped to the Google page, and typed:
late night food, los altos, cawhich took me to Bay Area Late Night Eateries which listed The Boardwalk for Los Altos, and included its address, phone number, and hours (open till 1am).
While it started out as a pizza place, the Boardwalk now has burgers, salads and sandwiches; including a very good Pastrami sandwhich. While it wasn't The Hat, it was a good thin sliced hot sandwich. Definately worth a repeat.
