Oh don't go to the 6ix. Unless the only other choice is the Hilton 24-hour joint! 6ix draws a bad crowd too, same a-holes that are at the tables in Bally's.
If you want good service mid-Boardwalk, go to the Roy Rogers- type place at the WWW and get a hamburger or two. The Asian noodle bar as Caesar's isn't bad either, and Nero's upstairs if you want to sit down a while and eat something fancier.
Uptown- I like Breadsticks at Resorts, service is tolerable and the food is near Greek diner-quality.
Downtown- Zeytinia's market in the Quarter at Tropicana. It isn't cheap, but being it is self-service the service will be good, and the food is too.
