Perma has a good bread, which is not something easy to find in China, at least for a European.
Now in truth the bread is ok, but is nothing that would stand out in Europe and the price is indeed quite expensive for bread. But considering that you are in Guangzhou and that no other option is available i guess is the best you can have.
Not a good experience overall. We've struggled to get the attention of the waiter despite the place was half empty. After we've waited 30' for one tacos and some nachos. The waiter didn't provide any glass for the beer, nor forks or knife, no peanut or anything while waiting.. nothing. The food itself wasn't anything special, quite bland. I don't suggest to go there for food. Many kids of around 20, maybe a good place for them to socialize.
Not pretentious but quite modern. There are basically 2 kind of noodles to chose. Dry and with soup. Both quite cheap and good. There are several beer options for this kind of noodleshop also cheap, some good local beer that aren't another lager. The enviorment is quite refined (of course cosidering the price of this noodleshop). They also sell some foodstuff imported from Japan. Not bad
