Clemente is a real Sulmona institution, and I called to make reservations even before we got into…read moretown. Its a Michelin-noted, white tablecloth place with impeccable but cordial service, and a great menu. It's also very popular with locals, many of whom were in evidence, ordering their "usual" dishes.
The portions are decently generous, and one of ours came with unexpected bonuses. The quality of the food was always high, and the execution ranged from "good" to "very good". Unfortunately their signature farfalle dish was the one that impressed the least; other dishes we had were more characterful. Great wine list with lots of Local, Italian and some international choices.
This is a real Sulmona experience, and worth considering if you'll be in town.
