Brown sause noodles are noodles, that are usually eatten without soup.

It's mostly like eating pasta, expect the sause is a bean sause instead of tomato sause.

The sause can be sweet, but not too sweet. The best way to describe it would be like eating a bunch of noodles with teriachki sause on them (expect them to be a little different tough lol).

Really the brown sauce noodles can not be told, it can only be tasted (Matrix rules), so you'll have to go and try them yourself. I think they're great, but you'll have to try them yourself to see what you think.

Hoped this helped
