Late nigh options are limited in. Grenada, but the Owl, as the name suggests, is a great spot to hang out for a drink late at night. It's literally on the beach, and if you're the adventurous type, stroll down and take a dip. They have a good variety of finger foods, and tons of great drink.
Nice chill spot, to watch some sports. Could be loud at times, with bratty college kids.
