We started going here on walks, and the service seems to be the same all the time.
Workers seem meh, not excited, but not quite dead.
The Slurpees are always frozen, cups and straws loaded.
The donuts can be fresh, or resemble rocks from the Mesozoic period. Kind of a crap shoot there.
Parking lot is usually dirty, but the inside seems clean.
For coffee I'd go across the street to AM/PM. Sodas are good, try the Jamaica Mexican Juice. Mmmmm.
