After going to American Express and Bretton Woods to get Euros, I called Wilshire Coin to see what their rate was and found that not only were they the BEST exchange rate I found in Los Angeles, but their service was excellent, and they were in Santa Monica, not downtown!
They have TWO parking spots in front of their location, but plenty of metered parking. The entry is so secure that you must allow a the first door to close before opening the other. Getting my Euros for the best rate in less than 5 minutes in multiple denominations made the pain of paying 36% more for 1 Euro priceless!
Note that they are open some Saturdays but you will pay more if you go on a week-end since markets are closed.
