I spent a month on a medical school rotation in this neighborhood-- a part of town I probably never would have found myself in otherwise. It turns out to be an interesting place, home to some great food places, including Pho Ha Nam.
It's located on the first floor of Asia Town Center, which doesn't look like much from the outside, but don't let that scare you. This little restaurant is a great spot for lunch! Both the #1 (eye round) and #3 (eye round and flank) are excellent. If you're not in the mood for pho, I can also vouch for the summer rolls, which have shrimp and pork and come with a yummy peanut sauce. Pho is under $9 for a gigantic serving-- I could barely eat half-- and the appetizer options are under $5, so this is a budget friendly lunch. Not a ton going for ambiance, but it's clean, and the employees are very nice.
Good pho is hard to find-- it's worth an adventure to this strange little mall to try this out.
