I love this place. They don't quite offer catering service, but I've ordered a couple dozen for parties and meetings before. Each time they were met with rave reviews!
I also attended a large benefit dinner there. Massive compliments to the cooks and servers for being able to handle so many people so easily!
The curtido and red sauce are excellent. The pupusas themselves taste like deep-fried heaven! Service is wonderfully quick and you can easily feed four people on less than $20.
The owners and cooks are also some of the sweetest people I've ever met.
