The first time I visited Sonoma's was for dinner. I got a great sandwich and some wonderful spinach dip, but even that time of day, it was way too smokey. I then went back one Saturday night to catch a band, and was amazed that it was even smokier. It's a small space, way too tiny for a band, and gets crowded very quickly.
I recommend for dinner or happy hour, but don't plan to go back for a night out anytime soon.
