Decided to check out Num Pang yesterday after hearing relatively positive things about the food.
Because they are newly opened, I was willing to cut them some slack on service (which they definitely needed...) However, I was shocked by how rude the guys (co-owners?) were to the customers.
Service was slow, as expected. It took ~15 minutes for the 10 people in front of me to order and then another ~20 minutes for them to call my number for me to pick up my two sandwiches.
While I waited, they called the number of a man who ordered before me. After they called the number a couple times, the customer asked if they were calling the number for a vegetarian sandwich (a rather innocent question...). The cashier responded, "I don't f-ing know man."
Food itself was decent, way salty, and too small for a really satisfying lunch.
