Allin's diner is a classic mom and pop diner. It's cozy and small. It was busy when we went on Sunday morning but we were able to sit down right away. We received service immediately and then got our food quickly. I got a breakfast of bacon, eggs, hash browns and toast. I wish there was a menu option to get all of that with a pancake! Overall we had a nice time and prices were very reasonable.

Stopping at Allin's Diner for breakfast when I'm in the STL area has become a tradition for me. Always look forward to a great meal and great service!

Everything was amazing and I walked out satisfied. I drink a lot of water and they did not neglect my need for multiple refills. It was so cute and quaint inside and had a homey feel.

Among my top three favorite for breakfast in the county! Great biscuits and gravy. I've had a lot in the area and these are my favorite. Great food and friendly service!

We were very hungry after an early hockey game at Centene Ice Center at Maryland Heights. And I've always drove past Allin's so it's time to try it today and we were not disappointed.. it's a small diner and the ambiance is great! We tried the Denver omelette, sausage and egg, french toast and my order Eggs Nuevo. Everything tastes ALL good and freshly made! We ate every bit of the food, it's that good. This is a great place! Highly recommended..

What a nice little spot and we were expecting decent food but we were really impressed! The biscuits and gravy were smothered with great flavor, the French toast was the best I've ever had, and the sides were cooked to perfection. The space is smaller so on a weekend fills up quick but it is definitely worth the wait compared to some of the chains in the area.

Allin's has become my go to breakfast joint whenever I find myself in St. Charles. I've been five times now, all on weekdays so I don't know what the weekend crowd is like. The diner is relatively small, but I've never had to wait for a table and there are some seats at the counter to be had as well. My service is always fantastic. I believe the young lady who normally waits on me is named Casey. She's a sweetheart and is everything you want in a diner waitress. I've never had to ask for more of anything as she's always on top of it. I've only eaten breakfast food and it's excellent. Pancakes are solid and the eggs are always cooked correctly. This may also be the only place that asks everytime if you want your bacon done crispy or medium Always spot on and worth the visit.
