What is the ruling on eating in the street?

Eating in the street is permissible, but people of murūʾah (chivalry/integrity) should avoid it if it is considered undignified in the custom of their locality. Murūʾah involves observing circumstances to avoid anything that is ugly or blameworthy. Murūʾah has been defined as "adopting the character of one's peers in their time and place," and it varies according to individuals, circumstances, and locations.
