Just for steak alone it's Jut'z. I had three steaks, all ordered rare, all came rare. Malo's one ordered rare, got it med/rare.
350 gram rump, quality the same at both, I guess they buy from the same supplier. Yut'z 110,000, Malo's 135,000. So if $2.50 is important another win to Yut'z.
Now, if your companion isn't into steak (and my wife isn't), the chicken at Yut'z is very good. However at Malo's they offer a Pizza that redefines Pizza, this place could claim to have the best Pizzas in Bali, or Melbourne for that matter. If we were staying on I'd go back for the Pizza alone.
Anyway that's it, both superb restaurants and ignore anyone who says one is MUCH better than the other. Neither will disappoint.
