If you attend concerts at Severance Hall in Cleveland, as my wife and I often do, celebrity chef J Sawyer's Trentina is the best restaurant within walking distance. It is in a small house with an outdoor pizza oven behind. Inside, it is cozy and well-lit (at least before sunset, when we went). The "granchio d'estate" (summer crab) appetizer, the "duck two ways" and the ice cream + espresso desert (I don't remember it's name) were outstanding. The "gnocchetti sardi" (Sardinian mini dumplings) were also good, though not at the same level as the rest. Service was amiable and prompt. Portions were relatively small by US standard - but in general, we feel this standard should decrease anyway! Not inexpensive, but the quality was commensurate.
