Antipuqueño Restaurant (also Intipuqueno), web site, 2504 Ennalls Avenue, Wheaton, MD, 301-942-1129 (web site says place is for sale)
This place is a total wreck and mess when it comes to service, décor, and organization. They also serve the best pupusas I’ve eaten in the U.S., ever. It’s worth it. The soups look pretty good too. The menu is ghastly in its presentation and it doesn’t list a lot of what they serve. Just try to talk your way into what you want to eat. The cute waitresses will giggle and mess up your order, but they do know what a pupusa is. I call this a find, though you need to go with the proper expectations.
