I frequented this particular location for a good stint of time (it was by a job of mine) and always had overall good service. The drive-thru line was almost not worth its wait half the time - just pull up and relax in a carport.
Servers are always friendly and food orders came out correct. Promptness was really a wild card -- I also came here mostly for lunches, so I did expect it to be busier. Sometimes it was quick service, sometimes I'd be on the edge of pushing that little red button when I saw someone skating out with my food.
I will admit, though, the food always came out hot and always tasted delicious. No bad experiences in that department.
Route 44 Diet Ocean Water is seriously my lifeblood. Just have to throw that in there.
