I second and third Juquila for their amazing food (and ambiance) but it's a different story when trying to order over the phone for a delivery. The manager seemed to want to scam us, so we ended up walked over to the restaurant to sort it out. But other than that, excellent excellent excellent.
Also, probably more Corona than J-Heights but Tacos Morelos is solid. Their camarones diablo is like a delicious fire in my mouth.
And, my weeknight go-to because it's quick, cheap and tasty: El Toro Bravo. It's perfect with each meal and the people who take orders are always ontop of things.
