It’s quite difficult to find local authentic Chinese food/restaurants in the UK; luckily this small business in Oxford, run by a person from Mainland China, strikes a perfect balance between quality and price, providing a premium deal during the lunch hour. For an extra 3 quid, Fusion House offers a wide variety of choices from rice dishes to noodle soup and stir fries, with some meals offering an extra variety of side dishes (though it does come at the cost of less options for your main).
I’d strongly recommend however, that when you go to these kinds of restaurants, do note that the experience is always better with larger groups. Meals are often portioned around communal sharing, as Chinese culture often encourages food being shared between your family and friends. Despite that, those who seek a quieter lunchtime break can still come here for the quality deals they offer.
Overall, it’s hard to find yourself dissatisfied. They can satisfy your needs to have a simple meal or beg a great choice to host larger gatherings. The staff were kind, service was good and efficient (though you might have a bit of an issue when it comes to allergies, as dishes tend to mainly be made with the same few seasonings and sauces, so do bring it up with staff if needed).
