I've been, went with my sister who spent 5 years in Bolivia a month or so ago and she claimed these salteña's to be the best she's had in the DC area!
We only had the salteñas, tried all 3 varieties (chicken, chicken and beef, beef), we liked the beef best.
El Antojito is 2 doors down from Mannequin Pis.
They can make them frozen for you to cook yourself, I've ordered 60 to take down to my niece's graduation party, the bolivian side of the family is attending, I hope this is a nice surprise!
Four stars for the salteña's alone!
