One comment on “Chowhound”
Chowhound is one good source among many others. I found Tripadvisor, Egullet, Yelp as useful as Chowhound. The thing is to always remember that we all have our own personal expectations, and that despite all the best intentions of Chowhounders, Yelpers, Tripadvisors..etc, you need to know what you like and what you do not. I have friends who sometimes rely only on other peoples opinions. Other peoples opinions are just that: OTHER peoples opinions. They are infos that should be used as tools to get better informed but other peoples can’t decide over your own preferences.
