I've been there several times, and it's conveniently located in the center. There are always visitors, reasonable prices, a good selection of freshly prepared dishes and drinks, and comfortable seating. I liked the interior. You can come have lunch with the kids.
The dining room has an advantageous location, close to the railway and bus station and, therefore, there is always a good flow of visitors. When I visit Petropavlovsk, I also always go in to eat soup and pies. The food is quite good, you can choose, I treat meat dishes with caution, and borscht, vegetable salad and pies with cabbage and potatoes are what a hungry traveler needs.
A wonderful inexpensive dining room, a very convenient location, as there are train stations nearby. We periodically come to Petropavlovsk and eat here. In general, the place is a good 5 stars.
