Hamburger Mary's is a fun restaurant that is always packed with people. The food is delicious from hamburgers to gorgeous looking salads to healthy dishes to choose from and the deserts are yummy too! There is an outdoor bar/patio where you can dine or order drinks and chat it up with your friends.
There is a dance floor/entertainment area that has something on every night of the week. There are line dancing classes, karaoke nights, general dance nights. Hamburger Mary's also has a clogger group that performs during events in San Diego. I also, believe, they have a softball team that plays in a league of other local businesses in the area.
Parking can be tough, for it is in the heart of Hillcrest.
