areas that have plenty of eateries/street food within walking distance?

Any suggestions on areas that have street food vendors and eateries within walking distance in the area?

I've lived in Ari, Saphan Kwai, Thonglor and Silom and I found Ari and Silom to have the most amount of action in regards to this.

Looking to base myself in a new area so open for suggestions and insights!
