Well, I always use them when travelling, since they don't have any restaurants in Australia at all. :-)
When I visit the US, I usually find there are quite a few restaurants in most places I travel. There must be over 100 places in the Seattle region. ... and some of them are very nice while some are very good value.
Taco Del Mar used to be a member in the Seattle region, which was great for getting a large number of cheap visits for those bonus promotions. Shame they aren't in it any more.
