The greatest human achievements have resulted from serendipitous fusions, such as chocolate chips falling into cookies and Santa Claus trying on a Hawaiian shirt. Experience a haute culinary combo with today's Groupon: for $15, you get $30 worth of international fusion fare and drinks at Retro Lounge & Grill in Freeport.

Opened in 1939 by entertainer and vaudevillian Al B. White, Retro Lounge & Grill now forges fusion cuisine with an internationally inspired menu. Meld genres with appetizers such as vegetable tempura ($8) and piñata-friendly baby lamb lollipops ($9). The shrimp yuccanut entree ($15) swims in a coconut-cream sauce before pairing up with a side of mashed yucca. Retro Specialty chicken wings ($6–$20) strut with an array of seasonings, including jerk, oriental, and traditional buffalo. Diners can satiate sweet teeth on a slice of bread pudding drizzled in maple syrup and served with vanilla-bean ice cream ($7).

Flaming red walls and matching booths punctuate rows of white linen-clad tables and glow with sultry memories of the early days of jazz. A stocky stone fireplace roars interior-design tips from behind plated glass as diners sup and swig.
