Jolly, in the banh mi thread (http://www.chowhound.com/topics/542371) expressed deep sorrow at moving to Los Angeles from SF and expecting wonder and excited to explore and getting disappointment. Jolly is now eating at Chipotle. Fie, fie on Chipotle. My heart weeps. Jolly, the Chowhound community owes you to get you back up on your feet.
First, where are you located, and what are you disappointed in?
I heard you express disappointment in: Central American, Persian. What else?
Some sure-fire suggestions:
For some reason, none of the Persian places in the Westwood area stand out to me. The Lebanese-Armenian place, Sunnin, on the other hand, bends my mind backwards. I worship at the feet of the cooks. Avoid: shawarma. Get: lebneh (whipped cheese) (ask for it with fresh garlic), fried cauliflower, that tomato-eggplant substance, falafel, the thing made of meat and cracked bulgher pounded together, and the best b'tilla in town. Phyllo dough, chicken, cinnamon, nuts.
The other Armenian favorite for me is Skaf's Grill - in Glendale and in the Valley.
Central American: there are lots. I'm currently engaged in trying to eat at every single Salvadorean place in East Hollywood. The gold standard is still Atlacatl, on Beverly. Get: pupusas, empanadas (plaintains filled with condensed milk and deep fried, sort of an ur-Twinkie), casamiento (best rice and beans and fresh crema ever), fried yucca topped with fried pork rind, and chilate - plantain and yam stewed in honey, with atole.
For an aside, in the Latin-American world, try Peruvian - Mario's Peruvian is my longtime favorite - for perfect fried squid and seafood saltado, along with Pollo a la Brasa on 8th and Western for wood-fired chicken, but the new contender, that I've been to only once, is Puro Sabor, which is spectacular.
Tell the rest of your disappointment, and we will provide.
