Fonda, a new Mexican restaurant on 7th Avenue between 14th and 15th streets, is in the midst of a “soft opening,” according to a couple posters on Brooklynian. No word yet on prices, but a blackboard inside the restaurant touts Mexican burgers, fresh guacamole, zarape de pato and pork in adobo as “signature creations.” The eatery is in the former Little D space.
