I'm visiting a friend in LA (Pasadena to be exact) next weekend for 4 days and I'm really excited to try all the food LA has to offer. My friend plans to take me to Thai Town and Little Ethiopia and I've already decided to have sushi at Sushi Gen in Little Tokyo (please don't give me any more sushi suggestion...I've already changed my mind about 50 times! see post: http://www.chowhound.com/topics/424201). I'm pretty adventurous and would really like to try things that are unique to LA or that you feel LA does better than Boston. I know I want to try some Mexican (Boston lacks this) but my friend doesn't know where to go, any suggestions? What other cuisines/restaurants shouldn't be missed during my trip? Please keep in mind that I will only be there for 4 days and there is only so much food I can eat! Also, I would like to steer clear of fine dining restaurants and mostly hit up ethnic cuisine/LA specialities that I cannot get at home. One last request (am I pushing it?): I'm not familiar with LA so it'd be great if you could provide me with either the addresses or neighborhoods of your recommendations. Thanks in advance!
