Any restaurant where you are seated and have a waiter is a TS (even though all you order at any buffet is your beverage.

A waiter still takes your dirty dishes away and keeps your glass filled). The only exception is the Pepper Market at CSR. There you are seated and a waiter takes your drink order, but it is considered a counter service. The waiter still expects a tip though. Beaches and Cream is just a hamburger/ice cream parlor, but is still a TS restaurant and counts as such on the
DDP, because you have a waiter.
