I have my 7 year old niece for the weekend and would like to take her out for an early dinner or even lunch at a fun Mexican restaurant in Philly. I'd like to be able to park easily ( safe street parking), and have a drink. She absolutely LOVES beans, so excellent beans are a requirement. (I make her red beans and rice and black bean soup regularly, so she knows her beans). I haven't been to any of the places in the S. Phila area that serve Mexican or even Colombian. I'd love to try something new. Casual and laid back is preferred, and obviously child friendly. Any suggestions?
