We found ourselves in Littleton on the rainy Saturday of Labor Day weekend headed to get groceries. Town was busy with holiday makers but we made our way, drenched, to the diner for a late lunch (who goes grocery shopping on an empty stomach)? I ordered a hamburger and himself had a corned beef panini. We were very pleased with our selections and enjoyed every morsel. My burger was moist, cooked perfectly and really superb - perhaps my gold standard for burgers. Himself liked his panini but loved the bite from my burger better!! We've eaten here in the past and will come back when we're in the area. We were seated immediately but we were there between lunch and dinner service. Our waitress was pleasant. Please note that this is a CASH only establishment.
