It is a cash only place! Customer service is good especially because the owners are on the floor serving, taking orders, and giving receipts themselves too. They are very friendly. The food is fresh and hot, and there are many options. I've been here for dinner, and gotten the sets and it was plentiful, and delicious. Today I went for afternoon tea and got the eggplant e mein noodles, fish slices and thousand year egg noodle soup, and lo mein beef brisket. We also added a plate of fried fish skin, so delicious and crispy!
