Sushi-Teq in the InterContinental has figured out how to combine the arts of tequila, salsa and sushi into one surprisingly sensual trio. On "Tequila Tuesdays," starting June 2 and running weekly until August 24, the restaurant will offer complimentary tequila tastings and free professional salsa lessons outside along the promenade overlooking Boston Fort Point Channel. On rainy days, the event unfolds inside (617-747-1000).
