Ambiance: 4. Small and intimate both inside and out, the new restaurant allows you to feel connected to the neighborhood surroundings as well as the wait staff and cooks. We sat outside with a great backdrop of the botanical gardens and Glidden House next door (along with a seemingly full working outdoor "kitchen') which I highly recommend (far more spacious than what can be a claustrophobics nightmare inside). That said, one caveat is the bianco and pasta tasting menus are only available indoors.
Cost: 3. Foodie-sized portions are taken to another level here versus some other spots in Cleveland. Also, tickets for the indoor tasting are more expensive for walk-ups than buying tickets online ahead of time ($100 for bianco) - fair? Probably not. The staff, experience, and of course food are no doubt are the cause of the extra money you're spending... which felt well worth it.
Food Quality: 5. Trentina's menu is modeled after Northern Italian cuisine. We had salad, the infamous Strangolapreti, lamb shoulder, and beef brisket (true outside grilling fun). All were A+, except for the lamb shoulder which personally was just a little on the fatty side for me, even understanding it's lamb. For desert, try the olive oil ice cream, it's fairly dense but a delicious gamechanger.
Service: 5. Service was prompt and courteous. Both J. Sawyer & his restaurant manager were heavily involved making sure both patio and indoor diners were happy.
When to return: Showing off Cleveland to foodies. Summertime to sit on the patio. Small group special occasion (the inside seating is limited). When you need a break from the E 4th / Ohio City / Tremont food scenes.
