How long? Owner Soo Lee says she's been in the same spot for six years.
Most popular: The bulgogi cheesesteak ($3), mixing Philly's signature sandwich with the Korean staple of marinated meat. We're also fans of the beef bulgogi platter ($6.50).
Noodle mania: There are 34 noodle dishes; we like the thick udon ($5). Non-noodle dishes, such as the hot and spicy stir-fries ($5), come with a huge pile of rice and two fried dumplings.
Must-get side: A not-too-spicy cup of kimchi for only $1. It pays to wait: Hit up the colorful truck after 3 p.m. - all platters are $4.
Fun fact: Lee has three children in college, so she understands why it's important to keep her prices low. "The kids are hungry and they don't have money," she said. "I'm trying to get them full so they can study."
