LTU and Ivans are on the fancier side but Negril is very casual so don't let your attire keep you away. Seastar is not as fancy. I guess you could think of LTU and Ivans as fine casual dinning and Seastar as casual dinning. You can take a cab from Rick's to anywhere on the west end and it will run about $5US per couple (make sure you negotiate price before getting in the car). You can always see if the restaurant you want to go to offers free pickup and then it won't cost you anything if you need a ride to get there.
