If your username is anything to go by, I'd recommend Darryl's Corner Bar & Kitchen. I really like this spot. But have not been there since the pandemic started.

From Kendall it's almost like a straight 30 or 40 minute walk down Mass Ave. Or you can simply catch the No. 1 bus. (https://www.mbta.com/schedules/1/line). Or just Uber it. With the subway you would have to change lines (Red to Orange). I think the Mass Ave stop on the Orange Line is the closest stop.

Good food, drink, music and people:
