foreign currency exchange

Does anyone know the best way to exchange euros (cash) into American dollars, in the United States? Bro needs to convert some of his euros, but the one travel agency in town which does currency conversions keeps saying that their "system is down". I checked at my bank, but they charge a $16 fee and their exchange rate is very bad (plus it would involve them taking the euros, mailing them off somewhere, and when it is finally processed, adding the money to my account).
