First it was open, then closed, then open again under new ownership. Let’s use our patronage to keep it afloat, if only for the 45-seat roof deck within a homer’s distance of Fenway Park’s right field wall. The reopening has come with a revamped drink menu and half-priced apps from 10pm to 11pm daily. Eleven flatscreens still let you catch the game as you enjoy the signature all-beef hot dog. It can get crowded, but not half as crowded as Yawkey Way before game time.
