Ritz is a fast food type of restaurant (and so are every other Caribbean restaurants I know). They have pre-made selections ready to scoop out into a container at your command. There are spaces for sitting and you can also get take out.
I had Jerk chicken once and also Ackee and Saltfish, both times with rice. I love their seasoning on their jerk chicken. It has a small kick but not overwhelming. You can't really tell what A&S is just from looking at it but it tastes just fine. It's my first time trying A&S. It's good but I find their ox tail and jerk chicken more savory.
My only real complaint is that they shouldn't chop up the chicken. It's fine to just serve me the whole piece of quarter chicken. The way they cut it, you might bite into bone shards. Also, I'm used to eating Persian rice or Korean rice. Persian rice is light and fluffy. Korean rice is round and a little sticky. I'm not too fond of the rice at Ritz but it may just be a personal preference. I find it a little dry.
Prices are alright. A large jerk chicken will cost you a little over $10. It comes with tons of rice and is about half a chicken. A small jerk chicken is quarter chicken.
I love to explore new cuisines. If you haven't tried Caribbean, I recommend Ritz as your starting point.
