It's quite rare to find an exchange place where the rate you get is only 2 cents away from the spot rate at the time, and no additional fee if the transaction is over $300 USD (I bought EUR). They give a receipt too. Although there's a 24/7 machine around the corner, was told that the shop offers a better rate (didn't verify this though, but thought of mentioning it here). I'll go there again.

Came here for some Euros and they had the best deal in town. Also helps they are open later than most. This has become my place recently because of their unbeatable rates. I usually call around, and they always beat out the competition.
