(FAIL) "Find Starbucks on La Cienega Blvd" --> "Couldn't find La Cienega Blvd in LA"
(SUCCESS, sorta) "Find Starbucks on Pico Blvd" --> "I found X Starbucks fairly close to Santa Monica" ...Pico Blvd stretches across LA, so I'm not sure why it chose Santa Monica except that the addresses start from there and go up.
(FAIL) "Find Starbucks on La Brea Blvd" --> "...X of them are fairly close to La Brea Blvd, Savannah, Georgia" ...apparently Georgia is on Siri's mind
(SUCCESS) "Find Starbucks on Hollywood Blvd" --> "I found X places fairly close to Hollywood Blvd"
(SUCCESS, sorta) "Find Starbucks on La Tijera Blvd (couldn't understand me, had to edit)" --> "I found X places on La Tijera Blvd, Ladera Heights"
(FAIL) "Find Starbucks on Vermont Blvd" --> "I found X places a little ways from Vermont Blvd, Elkton, Florida" ...Siri really wants to visit the south I guess
(SUCCESS) "Find Starbucks on Vine Street" --> "I found X places fairly close to Vine Street"
(SUCCESS) "Find Starbucks on Santa Monica Blvd" --> "I found X places fairly close to Santa Monica Blvd"
Those are all major streets in LA, but the results present a pretty underwhelming success rate.
