I think this is a fantastic small place for lunch. The food is basic but good and homemade. The price is right for an appropriate size for lunch. I got the homemade basil and tomato soup and a half sandwich for $5. It was the perfect size without feeling completely full. The salad is also pretty good.
There's so many fast food joints in downtown Pittsburgh...Apollo Cafe is quite refreshing for a lunch option. I will keep coming back here.
