Was in Bali in March. I was really impressed with how great and affordable the food was. The best restaurants, comparable to most any fine dining you'll find at home, would run the two of us $50-$70 US. This is delicious, full three course meals.
My favorite restaurants were Sarong in Kerobokan and Chez Gado Gado in Seminyak. You'll want to make reservations as soon as you arrive. Sarong especially was booked solid every night, for good reason.
The Living Room in Seminyak is probably the nicest restaurant setting you could hope to find. Food was quite good, but on the more expensive side. The whole place is lit so beautifully though, it was a nice experience.
Have a great time!
