Kuppy's Diner is a really nice little place in the heart of Middletown. Just finished having a hearty breakfast there (ham & cheese omelet, home fries, toast, with an extra side of smoked sausage). Everything tasted really good. Service was quick and friendly. The decor is a welcome blast from the past; this is very much an authentic diner, not some re-creation of one. There are framed displays of write-ups about the place's extensive history on the walls, displays that let you know you're helping to continue a tradition. Seating comes in a nice variety: about ten stools at the counter, six booths, and four tables with chairs (which comes in handy for those, like me, who are rather larger). I'll definitely be back there to try another meal.
