Best Nightlife: It may be tiny, but Pacchia's Jazz Room packs a big punch. It's everything a jazz club should be: dark and hazy, with good acoustics. The overall ambience is continued from the restaurant — stylish and contemporary without being too pretentious. It tends to get packed at times, but you can count on hearing the best jazz in Dayton. So after you savor Mediterranean-inspired cuisine at the restaurant, duck into the Jazz Room for some straight-ahead music. A truly cool way to spend an evening!
