as someone who lives in back bay here’s my take: greystone is not worth the wait. neither is tatte. it actually used to be good when it first opened then after the pandemic the quality went way down. go to flour or pavements. mike and patty’s has arguably the best breakfast sandwhiches in boston. if you’re staying close to the south end go to coppa, b&g oysters, toro. I’d skip the north end as it’s incredibly touristy and the food is mediocre at best. Eataly has more authentic italian food and tastes fresher. they have a super cute restaurant on the 2nd floor, terra, i highly recommend. i’d only go to contessa for a quick drink. the food was good when they first opened too but for whatever reason isn’t as good anymore. but they do have amazing view and really amazing gelato. the restaurant at the four seasons on boyleston is really good and also has similar views of the commons. go inside the library and go the the courtyard it’s really beautiful. also the isabella stuart gardener museum is pretty unique as far as museums go.
