Not something worth searching for by any means, the Starbucks in Shimokita is at least a reliable source of wifi(if needed) or quick and easy bathroom stop. But it could also be a lazy stop for tea or coffee. When my girlfriend and I were last there, it was raining non-stop and we were desperate to just sit down for a second. Seating looks sparse when you first walk in but note there is another floor of seating the next level down.
