Best cold Vietnamese spring roll in Hollywood/East?
Personally, I haven't found any good ones in Hollywood/East. First of all, I would stay away from the word "cold". Many places serve them cold by sticking them in the fridge or keeping the ingredients too cold. A good spring roll should be more like room temp. Another thing some restaurants do to 'cheat' is put a bunch of noodles in the spring roll. I would rather have more veggies and meat than noodles. If I want noodles, I order Bun.
If you really want to try the good stuff. Go to Alhambra and stop at Nem Nuong Kanh Hoa on Valley Blvd. You can get an order of spring rolls for about $3.50. They have amazing BBQ pork in their spring rolls and they also add fried shrimp rolls. You can also order a plate with all the ingredients to 'roll your own'. For about $12 you have enough food for two people.
I drive there every week and it's always a treat. They also have great Bun Bo Hue and the owners are extremely nice.
