Health food? Not here. The street vendors in Barrio Antiguo don't sell tacos or enchiladas. The don't sell burritos. They sell hot dogs. You can get them wrapped in bacon, with peppers and onions, with cheese inside.
Of all the street food I've eaten all over the world, these were absolutely decadent, but superb. Chicago dogs or whatever the famous hot dogs are in America just don't compare. If you go to Barrio Antiguo, get a hot dog. I don't care if you're vegan. It's worth it. :)
Favorite Dish They have good ketchup?
In the street, the food is regional food (tacos -gringas, piratas, of bbq, and bistec-, toast, regional candies, spiral potato chips) and fast food (hot dogs in the afternoon and the night, and burgers). In these sites the cleaning is not secure, english is not spoken, except few sites. If you want eat food from these sites, you must learn some phrases in spanish. Beloware some phrases and words
-Buenos días Good morning
-¿Tiene servilletas? ('ll' is pronunciated as 'j') - Dou you have napkins?
-¿Tiene salsa? - You have sauce?
