My boyfriend and I will be coming to town from Boston next weekend and I'm looking for recommendations for places that have good (but not serious or fussy) food and vibrant, lively atmospheres and clientele. We have had a very stressful few months and are in dire need of an escape. I care more about the food than he does, and I don't want to waste my trip to SF by missing out on great meals, but it's not the time for complicated menus or ambitious flavor pairings. I'm looking for delicious food in a festive setting--crowded and loud are good. Not focused on trendy, and nothing too young (we are late 30s and early 40s, respectively)--just want someplace where we can eat and drink and feel celebratory.
Thanks in advance!
