When I lived in University Circle back in 2005 - 2007 my roommates and I spent more money at Valentino's than we should probably admit; but we did it because the pizza is awesome and the service was above and beyond. Hands down, this is my favorite pizza in Cleveland.
Unfortunately, like many businesses in the food service industry, turnover at Valentino's tends to be high, and almost none of the people who made my Valentino's experience so great are still there. That's not to say the quality has deteriorated, as each time I've been back since the pizza and service have lived up to the standards I always knew. I just hope that never changes.
