Did you wake up to an interesting new e-mail from Google Wednesday morning?

Google has continued to roll out its coupon service, Google Offers, in five new areas including the D.C. region. Washington-area residents who have signed up for the beta got a half-off coupon ($3 for $6 of food) for an Adams Morgan restaurant, the Amsterdam Falafelshop, in their inboxes.

To use the coupon, you have to buy it by Sept. 9, 2011 and redeem it within a year, by Sept. 7, 2012.

Other cities that got access to the coupon site this morning are Austin, Tx., Boston, Denver and Seattle. Coupon-lovers in Seattle get a deep discount on admission to the Seattle Aquarium, while Denver residents get a deal on merchandise at the Tattered Cover Book Store.

Google announced Offers in May, launching its first beta-testing site in Portland, Ore. Since then, the service has been expanded to New York and the San Francisco Bay Area.
