There is nothing walking distance, you just need to download the local "uber" app, Gojek or Grab. Ungasan village itself is 5-8 minutes drive. There is a nice cafe serving mainly Russian staple, Ituaja. If you want a top restaurant, Di Mare at Karma Kandara is super nice, 10-12 minutes ride away. Avoid anything along Jalan Uluwata if you want to avoid traffic jams!
