I am definitely not an expert in Vietnamese food, just to put that out there. That said, I really enjoy Tea Lite Cafe. My co-workers and I go here regularly, and it is a staple in the portfolio.
I get the #1 and honestly don't remember its name, only the deliciousness of the rice noodles and beef. The beef has amazing flavor and I wish there was about twice as much included in the dish (not just because it tastes good, but also because I could use a little bit more protein to get me through the afternoon). We often get an order of the shrimp spring rolls to help supplement the lunches here.
The service is very fast. Important tip for weekday lunches: get there early! This place fills up quickly and does not have many tables.
