Jax for steak??? I ate at Jax on our March trip....and hadh a very good tasting steak...but the best?? I think not. Personally, i think Moulen Fou beats them for steak. Could be only my opinion....but willing to hear others. As for ribs and chicken....easy answer and close to Maho. ROSIES on Mullett Bay!!! Best on the island. Only for lunch though...not open in evenings. Burgers....right at LaPlage Tortuga. I had one of the BEST I have ever eaten at the new Tortuga. It wa absolutely FABULOUS...and i love burgers...but never get excited over one....until this one!!!! LOL Of course, it is more difficult to find a so so restaurant on the island than a good or great one!!! You didn't mention a more casual dinner in the area too.....for that I would recomend Fat Tony's near the Med School. FANTASTIC pizza, decent cheap steaks...ribs....chicken etc. Also on some nights some fun entertainment shows up. Always a fun night when you just don't want that full formal meal. Enjoy your trip.
