Lovely people. Super quick service. We had the pastrami burger and the garlic burger and they both were delicious! Portion was generous and included either fries or salad.

What a truly authentic and delightful diner! It is so clear as soon as you enter that the owners put so much heart, soul and sincere thought into every part of the diner. From offering a10% discount to seniors 55+ and veterans, to every dish being cooked from scratch--they advise you that your food will take between 20-30 minutes to be served--but it is so worth the wait!! They use excellent quality ingredients--I had a Denver omelet and it had real fresh cut cubes of ham and green and red peppers, onions and two cheese. Absolutely delicious! The roasted potatoes were crispy and fresh and the sourdough toast was exceptional. Even the coffee was excellent. Finally, the service was awesome and the staff were super attentive and friendly. I will make a point of coming back many times to come! Thank you!

Came through town on our way to Yosemite. Had a lovely meal in the evening. The atmosphere was great and the menu extensive. Lots of options for the family. Food came out quickly considering they were busy. Would definitely recommend.

We decided to check this place out during our visit to Yosemite/auto camp stay near by. My kids and I enjoyed to local vibe and character of this restaurant. Food was great for diner standard. Hamburgers and onions rings were generous and not to be missed. Milk shakes were favorite of my kids. I had the fish taco. On the smaller side - only one taco per serving but I ended up getting two to make it a meal. The service can be slow so plan ahead - our order took about 40 min to come out - around 7 pm. Definitely recommend when visiting Mariposa area.

Had an amazing experience! Truly so many choices. It was the perfect stop after a long day of hiking. Staff was happy and quick and the food was delicious. I had a paddy melt that was perfect and my wife's dream came true as she ordered chili in a bread bowl, a corndog, and chocolate milk, some of her favorite foods. We had a coupon for a free ice cream cone as well and what they made us was huge! Probably the best and largest free ice cream I've ever had! That alone shows the quality and class of the restaurant. We would definitely recommend!

On the way to Yosemite we were looking for a decent restaurant with an EV charger nearby. This area had one. Plugged in my car and walked a couple of minutes to have lunch here. The inside looked quaint and just like movies :-D We had ordered a sub sandwich (vegetarian) + salad, chicken ranch wrap + garlic fries + soda. The food tasted good. Veggie sub looked pale on the outside. Most likely it wasn't grilled on all sides. They have items clearly marked vegan and vegetarian. If you are strict vegetarian be sure to ask it at the counter as it seems all the vegetable oil is replaced with tallow (animal fat). Wasn't a fan of that but I didn't have any other option at that point. Overall it was a nice spot on the way to Yosemite and i may come back here again for a quiet meal while charging my car.

I ordered the 30yr anniversary special. Amazing burger, absolutely delicious. The woman who took my order was also very friendly despite a bit tired near the end of her shift
