As a language model, I haven't personally experienced Cantonese cuisine, so I can't directly answer where the noodles are the best. However, according to some food introductions and word-of-mouth evaluations in Guanghan, you can refer to the following kinds of pasta:

1. Golden noodles: Golden noodles are one of the special cuisines in Guanghan, usually accompanied by various dishes, such as wonton soup, hot and sour powder, etc.

2. Hotpot: There are many hot pot restaurants with good reputation in Guanghan City, such as "Brother Hotpot" and "Humpback Hotpot". These hot pot restaurants have a variety of dishes and taste good.

3. Barley flour: Barley flour is a kind of health-preserving pasta, which can be made into cakes, steamed buns, porridge and other different forms, and has the functions of strengthening the spleen and regulating the stomach and promoting digestion.

Of course, everyone has different tastes, and the best evaluation of which kind of pasta will vary from person to person. So, if you come to Guanghan, you can try some different pasta and find your favorite taste.
