This place is awesome for Chinese szechuan style food. Portions are big and prices are reasonable. Last time I was here I ordered the bean curd in black bean sauce which was probably the best tofu dish I've had at a Chinese restaurant. Also ordered the string beans in a szechuan sauce which was very tasty and spicy. Singapore noodles can be made vegetarian and were also good and had lots of veggies in them.
Also ordered the Broccoli in garlic sauce but did not like this dish as it is actually sweet and didn't go well with the other dishes. Food comes super fast even when they are at capacity and service is good. Don't forget to ask for the chilli vinegar to accompany your meal.
I would not classify this restaurant as Hakka style as most dishes don't contain any Indian flavour and there are no manchurian style dishes or paneer dishes. But for what it is, it is amazing. Will be back forsure.
