I don't really like sit-down places when I'm by myself.
I don't mind for lunch — usually I just want to get some work/play done on the laptop — sometimes for dinner, but if there's a ginormous crowd in the evenings, I steer clear...I get a gut feeling that I'm not going to great service because the resulting tip for waiting my table isn't generally as cost-effective as a group of four. Secondly, I've had enough noise and banter to deal with all day, and the last thing I want to do is hear a couple of LOUD LUSHES WHO DON'T REALIZE ALCOHOL APPARENTLY MAKES THEM PARTIALLY DEAF in the table next me (who are actually having a bit more fun than I am).
On the other hand, I think of the part of a movie (which title escapes me), where Steve Martin is introduced as a "party of one". He sees a friend at the restaurant later on, and asks him to join him at their table. "What about your bill?"...to which Steve pulls out a notepad just as the chef is coming by, assumes he's a food critic, and gives him a complementary meal.
In Florida, its Millers Ale House (a regional chain) where the Food is good and if you like Miller Lite there are $6 Buckets.
In Fort Lauderdale there is Lesters Diner on FL 84 between I-95 and US 1 that is good as any NJ Diner.
Then there is Golden Corral, but only Orlando, FL (at select ones) serves all three meals. There buffet is to die for.
The Miller's Ale Houses (usually they are named for whatever city they are located in, e.g. Jupiter Ale House, Boca Ale House, Miami Ale House)...and they do offer good food and service, and lots of seating for drinkers and non-drinkers alike. I met the owner back in my days as a service advisor, and he was an alright guy.
Lester's Diner (there's a satellite diner closer to home) is decent, good service, okay food, but definitely one of those places if you have no idea what you want to eat...hey serve just about everything. Great place to take the kids, and overhear the old folks as well...used to hit them up after a night of drinking and such.
Golden Corral doesn't impress me; if I go, I go to the one by my home. Sometimes I'm in the mood for it, but I kind of wish I could get my own drinks. The kids like it (although they seem to enjoy eating whatever's on my plate, rather than their plates).
