Mammoth Dining Room

We ate there early dinner at 18-Sep-25, ~16:30 (when the place opened). My wife and my son are vegans. This place shows all signs of a typical monopoly business. The food is not so tasty, and in small amounts. My son ordered pasta, but couldn't eat it as it had too much Parmesan cheese. The waitress didn't want to refund us for that, so we invited the manager, and she said we won't pay for that. The service isn't so good, and you wait a long time for the food. Prices are quite high, so the value for the money isn't good. We also ate breakfast in the same place, which was much better than the dinner. It's 20$ per person, self-service. You receive a glass of juice and black coffee or hot chocolate within this price

I really enjoyed my lunch at the Mammoth Dining Room. I ordered a cold, smoked salmon BLT, paired with fruit. A cold hard cider was very refreshing after a hike in the park. Danny, my waiter was very attentive and friendly.

Exceptional Service at Mammoth Dining Hall – Thank You, Tayla! During our recent visit to Mammoth Dining Hall, we had the pleasure of being served by Tayla, and let me just say, she was truly outstanding. From the moment we sat down, Tayla greeted us with warmth, a genuine smile, and an energy that made us feel instantly welcomed. She went above and beyond in every interaction—thoughtfully answering our questions, checking in at just the right times, and making sure our experience was smooth, relaxed, and enjoyable. It’s rare to come across someone who not only does their job well but clearly takes pride in making others feel taken care of. Tayla’s kindness, professionalism, and attention to detail didn’t go unnoticed. She represents the Yellowstone Lodge team beautifully, and we’re grateful she was part of our day. Thank you, Tayla! You made our visit extra memorable. Wishing you all the best! A grateful guest

I was with a tour group staying at the Mammouth Hot Spring hotel. We ate both dinner and breakfast here. We had a very nice dinner beating the crowd at around 5 PM. The food was tasty and definitely better quality than what we had at some of our other tour stops. Our server Quincey was excellent. The following morning we had the breakfast buffet which I cannot recommend. The food offerrings were limited and based on the number of people they served it really could have been much better. My personal issue was with the scrambled eggs. Do any buffet's offer real eggs any more. The egss were clearly something impersonating eggs. I ended up eating rice krispies ☹️

We were blown away by the soup of the day, which was steak & potato soup. Chef Jeff nailed it! My husband said it was the best soup he’s ever had in his life. Chef Jeff even came out and talked with us! Our server, Alexandra, was terrific, too! She gave us great recommendations. I had the crusted trout and my husband had the roasted chicken. Both were delicious! Even though I was so full, we had to try the lemon cake to go, which was really good, too. We were pleasantly surprised this restaurant in the middle of Yellowstone would have such top notch food and service. We will definitely be back!

Fun items on the menu compared to other park stops. Staff was overwhelmed but still worked hard. Shishito peppers and gouda soup were the highlights.

We walked in and felt excited to that there was such a nice restaurant in town. The dining room itself is lovely and the staff were really nice. The experience fell apart badly from there though. Our server was really friendly and funny but then our order got somehow cancelled after it was placed so we ended up waiting a really long time. After they apologised for that, they said they would get another drink but that was also forgotten. Then the food came and my meal was inedible. I got shrimp added to my pasta which was $9 and that was just 4 small pieces of shrimp which felt extortionate. I’ll say the shrimp was cooked really well so they were nice but the pasta it came on was awful. I can’t even work out how they have managed to get pasta to create a texture like that. It was extremely gummy and was sticking to my teeth badly. A very unappealing texture and confusing how it came to be which put me off so I didn’t eat that at all. We don’t like to make a fuss and send meals back so my partner forced it down instead of wasting the money and I just went and got snacks from the general store after for dinner. My partner’s meal was decent. He got the bison burger and said it was nice. His fries were cold but good otherwise and he liked them. It then took a while to be able to pay and leave so we got stuck there for a long time. I’m of the perception that they are possibly understaffed and it isn’t the individual server or staff members fault when things like this happen but we didn’t go back for our time there as we found the food to be nicer and significantly cheaper next door at the grill.

Comfortable and inviting dining room. Warm and cozy in winter. Service is generally good. Food quality is acceptable given the remoteness of the place and the fact that in winter it must be a logistical nightmare to keep this running. This is the only choice at Mammoth, but not a bad option at all.
