I finally went to Bali Noon Bali Moon in the Plaza House shopping center near Aeon Rycom Mall; they were on my list of places to try for awhile. The biggest reason I wanted to go: tempeh (テンペ ten-peh in Japanese).
This place makes their own tempeh… and it is sooooo much tastier AND cheaper than the packaged stuff you can only find at some of the hippie organic stores here in Okinawa! The tempeh taste was really amazing; they sell a 500g block for 500yen. Compare this with the 100g packaged stuff sold elsewhere for ~350yen, this is a steal. So for anyone looking for tasty and reasonably priced tempeh, Bali Noon Bali Moon is absolutely the place to go.
As for the restaurant itself, it was decent. I ordered the tempeh curry and my husband got the mixed lunch set. Both tasted pretty good, but it was a bit expensive for lunch overall in our opinion. That being said, Indonesian food is pretty exotic for Okinawa, so I can understand the price being a little higher than some other more typical restaurants. It is worth a go, overall, plus there are vegan and vegetarian options.
