Hands down my favorite place to grab lunch mid beach day is at Blue Fish. Its right off of 90th street which is my favorite beach spot so its perfect. I can just hop out of the sand and go grab a bite to eat and come right back within minutes. I have definitely developed a passion for walking everywhere when I am at the beach. I also love Bad Monkey for lunch at the beach. They have the best burgers and they have two locations making it more accessible depending on what street you are on. I have attached both of their websites below, so check them out.
