A restaurant for burgers, milkshakes and more has permanently closed after just over two years in Bethlehem.

Retro Burger updated its social media to reflect its permanent closure at 1223 W. Broad St. It offered no explanation for its closure.

The restaurant couldn’t immediately be reached for comment through social media or email, and a phone call couldn’t connect during its normal operating hours Monday afternoon. The restaurant also appeared to be locked up and empty Monday afternoon.

Retro Burger opened in November 2023 to replace The Mint Gastropub.
