Two things I recommend:
1. Tacos Adobada
2. Fries con Adobada
I love pork on my tacos and Tacos El Gordo does it right. Adobada I guess is a relative to al pastor or is very similar hence my love for this place. The adobada comes off a huge rotisserie, that they carve it off the rotating piece of meat and satay the carved meat. The tacos adobadas are topped with this spicy green sauce and pineapples [if requested]. 3-4 tacos are an adequate amount for a meal and a half order or french fries with adobada is a must.
Service is excellent - Make sure you tip them!
Best times to come - After lunch and before dinner otherwise it's a madhouse.
