Ellen’s Amusement Center entertains kids and adults with amusing activities such as go-kart racing, video games, and miniature golf. Go-kart drivers vie for first place during four-minute races, and up to four friends can cross clubs during 18 holes of mini golf. Ellen’s two-story arcade hums with the clatter of table-hockey pucks and occasional cries of “fore!” shouted by confused air-hockey players. Each batting-cage token grants adults and nonadults 20 pitches to improve their swings, with speeds varying from slow-pitch softball to 85-miles-per-hour hardball.

Though Ellen’s Amusement Center sometimes features a discounted price online, this Groupon is still the best deal available.
