Mercer Street Hospitality
Founded in 1993 by entrepreneur John McDonald, Mercer Street Hospitality (MSH) is a New York City-based boutique hospitality group with deep roots in the heart of SoHo. What began with the opening of the neighborhood's iconic MercBar has grown into a curated collection of some of downtown Manhattan's most celebrated restaurants and bars — each with its own distinct identity, united by a shared commitment to exceptional food, drink, and genuine hospitality.
Today, MSH owns and operates a diverse portfolio of venues including Lure Fishbar (New York & Chicago), Bowery Meat Company, Bar Mercer, Cha Cha Tang, Smyth Tavern, Galerie Bar, and Seahorse at the W New York – Union Square — the group's latest addition. Together, these brands span the full dining spectrum — from coastal seafood and upscale steakhouse dining to neighborhood taverns, wine bars, and inventive cocktail lounges.
For over 30 years, Mercer Street Hospitality has remained grounded in its original ethos: create places people want to return to, again and again.
