El Rinconcito or El Tamarindo?

Going to be passing through D.C. for the first time on a road trip and stopping for sightseeing and dinner. I saw recommendations for both El Rinconcito and El Tamarindo in my search for Salvadoran restaurants - which is your go to? Haven't had much Salvadoran food but LOVE pupusas. Open to other recommendations as well - ideally looking for sit-down casual, convenient parking is a plus.

TIA!
