I like this place A LOT.
I went to CMU and didn't have a car, so especially during freshman/sophomore years when my friends also didn't have cars, this was the convenient place to go if you wanted to go somewhere decently nice. But aside from the location, I really do like this restaurant.
The food is largely portioned and mostly delicious. No, not like delicate-beautiful-dish kind of delicious, but I've always walked away happy with my experience.
I've had a small variety of dishes here, including a burger, a fish burger, and the Californian salad. And since I've had my first Californian, I've stuck with it.
...and I am craving Union Grill as I type write this review.
