It's cheap, it looks like a diner and it's open every day in an area that at least has decent parking during the evenings. What more could you ask for? There is flavour (which I'm sure is partially assisted by MSG), lots to pick from, and takeaway containers when you aren't able to finish the meal.
On this occasion I had the Mapo tofu on rice, spicy eggplant with noodles, Shanghai fried pork dumplings and steamed vegetarian dumplings. Enjoy them with vinegar and chilli sauce and you'll be satisfied.
The food isn't as good or flavoursome as Red Chilli Sichuan, but that's another meal in another setting for another price tier.
