The climate in Cleveland is unfortunately not very conducive to outdoor patios, especially downtown, where space is valuable. I typically think Paninis is a mediocre-at-best local chain of bars. Most suburban Paninis locations are worth visiting only because they are the only place around (what did you expect in the suburbs?).
The East 9th Paninis get's my stamp of approval because it's the best patio in downtown Cleveland. It can be easy to get cabin fever in Cleveland, so when the weather turns, there's nothing better than sitting outside after work drinking a beer. Paninis is one of the few places downtown where that happens.
