This fish/seafood restaurant was recommended by our guide, a Torajan who lives in Makassar, after we entered the city following a tour to Tana Toraja. "Ratu Gurih" is a large open-fronted restaurant in the city centre, and when we visited on a Sunday evening, we were the only Western diners in a restaurant that was almost full of locals, including large groups who were eating following the end of the daily Ramadan fast. Given the clientele, it's unsurprising that the restaurant does NOT serve alcohol, although it has a range of soft drinks including some excellent fruit juices.
Fortunately, one of the staff spoke good English and we were invited to select fresh fish and live seafood from a wide range (including various fish, crabs, King prawns and clams) displayed at the entrance to the restaurant. We chose the King prawns, clams in chilli sauce and a whole fish, together with side orders of mie goreng and vegetables. The food arrived promptly and the clam dish was (thankfully!) totally uncompromising and searingly hot, the prawns were pleasant but not exceptional and the fish was rather a disappointment as it was overcooked and a little bland, so we resorted to the side dishes of firey sambal to impart some interest.
The final bill was around IDR 460,000 (c.£25) for 2 people, inc. drinks, which is excellent value for fresh seafood. I'd recommend this restaurant for seafood lovers who want to have a more typically local eating experience when dining in Makassar.
