Does Alan Harding, the king of Carroll Gardens, have a new project up his sleeve? We hear talk of an “upscale cocktail lounge” on Hoyt Street near Union Street’s Black Mountain Wine House. A neighborhood foodie tells us that this new venture depends on the community board, which will vote on the liquor license tonight. Sure enough, right there on CB6’s land-use committee agenda tonight is “Discussion and formulation of recommendation on an on-premises liquor license application submitted to the State Liquor Authority on behalf of 415 Union Street Inc. at 303 Hoyt Street (Block 430, Lot 78) between Union/Sackett Streets.” Will Brooklyn Social or another neighborhood competitor try to protest? Find out tonight.
