I really enjoyed the salad that I got at Hello Bistro today--the ingredients were nice and fresh and there were tons of options to add to your salad. It's a nice addition to the Oakland area lunch options, and I think it was pretty reasonably priced for the size of the salads. I also was a big fan of the Boylan Soda machine--it's nice to have different selections for fountain drinks.
The only complaint I have was how crowded it seemed to be--like there were too many people working all at once. It was also hard for the staff to hear you as you ordered things to put in the salad, but I ended up with everything on my salad that I wanted--so I can't complain too much, but I can imagine this problem only getting worse when all the students return to both Pitt and CMU.
