This place is awesome for exchanging currency. The staff have always been friendly, the service is fast and you really get the best deal in town coming here.
I've used them several times before going to Mexico and this last time coming back, I came back with money and exchanged it back to US. I guess I did not drink and eat enough in Mexico to come back with as many peso's as I did, but it was nice they were very friendly here and had no issue changing them back.
I highly recommend this place, its pretty easy to find and the new office they have is so much more welcoming then the other building they were in.
