"When: Monday to Thursday, open to close; Friday, 11 a.m. to 7 p.m.What: $6 beers, $10 frozen drinks Medusa is proof that Park Slope still has fun. The Greek restaurant has an upbeat party playlist with sea monster murals and tentacles hanging from its walls. An “all-day, all-night” happy hour is offered around the clock on weekdays with discounted beers and frozen margaritas. A number of dips, cheeses, and appetizers are available for around $10 each." - Luke Fortney, Caroline Shin
