Foursquare Tips

  • A wonderful place for anything from a business lunch to a family dinner. The food and service are good, and the atmosphere fun. Good location at Queen Ka'ahumanu Mall.
  • Feel like I stepped back in time. Nice place.
  • Try their malts!
  • Milk Shakes are absolutely Delicious
  • The buffalo chicken quesadillas are out of this world good!
  • Hostess seated a party of two that came in after me, then asked how many in my party (it was just me), and told me it'd be a wait. I took my business elsewhere, and don't plan to return.
  • The food wasn't great, but the milkshake was fantastic!! Defiantly a must-go for desserts!
  • Saturday lunch service is horrible. Go off peak or you'll get shafted big time.
  • The only diner in the entire world that doesn't serve breakfast till noon.
  • Good service, timely food, and the environment is upbeat for enjoying a personal meal or having a business lunch. Went there with my baby_girl on Thanksgiving Week and we got stuffed. Good times...
  • This 50's-style diner is on the outside of Ka'ahumanu Center (don't need to go inside the mall to enter the restaurant).
  • Grossest bathroom in all of Hawaii. Pretty sure employees are not washing their hands... That'd require towels, right?
  • Chocolate Coke and Vanilla Coke! Just like the old days!
  • Try a milkshake, they're good
  • Guacamole burger w/ onion rings
  • Did not like the food the third time around for lunch,burgers.The breakfast was great!
  • Mediocre service
  • Good grilled cheese
